While most bars prefer a credit or debit card to open a tab, you might be able to open a tab with cash depending on the specific bar's policy, especially if you provide a sufficient amount as a deposit. It is best to ask the bartender directly.
Tabs can be closed in a variety of ways: Credit/debit card: The payment is charged to the card provided at the start. Cash: Customers can choose to pay in cash, at which point the original card is returned to them.
Although each bar's policy on open tabs varies based on management preferences, most bars require customers to provide a credit card before opening a tab. In many cases, a bartender holds on to the customer's card until the tab is closed. This helps to ensure the tab is paid for at the end of the night.
When a customer places an order at the bar or with a server, your staff should ask if the customer would like to start a tab. The bartender or server then requests a form of payment—generally a credit or debit card—to secure the tab. No payment is collected at this point.
The cash register
Usually operated as the main payment point in most bars, and usually in the centre of the back bar where it is easily accessible by all food and beverage staff members.
Australia's new cash laws, effective January 1, 2026, mandate that major grocery and fuel retailers must accept cash for in-person purchases up to $500 between 7 am and 9 pm, ensuring essential goods remain accessible, though small businesses with under $10m turnover are generally exempt. These regulations aim to support cash-reliant Australians but don't apply to all businesses, with specific rules for essential items and transaction times.
The 1-2-3 drinking rule is a guideline for moderation: 1 drink per hour, no more than 2 drinks per occasion, and at least 3 alcohol-free days each week, helping to pace consumption and stay within safer limits. It emphasizes pacing alcohol intake with water and food, knowing standard drink sizes (12oz beer, 5oz wine, 1.5oz spirits), and avoiding daily drinking to reduce health risks, though some health guidance suggests even lower limits.
Every bar's policy is different. While some may allow you to open a tab with cash, most bars will require a credit or debit card to start the bar tab.
That said, a lot of clubs prefer cash for small purchases, like coat check or entry fee. Even though clubs will have card payment options for tables, it's not always the case that you'll be able to pay with a card if you're on the guestlist. That's why we always suggest keeping some cash on you.
To open a tab-you order a drink, usually at the bar, and instead of paying for it then, the bar keeps your credit card. The credit card is held and charged until you are done and ready to complete the transaction–this leads us to the next phrase.
Three fingers of alcohol is an imprecise, old-fashioned measure, but generally equates to about 3 to 6 ounces (90-180 ml), often estimated as 1 to 2 ounces (30-60 ml) per finger, with variations depending on finger size, glass size, and bartender interpretation. While some try to standardize it to 1 ounce per finger, a common pour for "two fingers" is 2 ounces, making "three fingers" roughly 3 ounces, though it can easily be more.
2-1-1 is a ratio of the three base components that make up a sour cocktail: 2 parts liquor, 1 part sweet and 1 part sour. If you prefer a stronger or less sweet drink, just adjust the components to taste, using the 2-1-1 ratio as your baseline.
The 30/30/30/10 rule for restaurants is a budgeting guideline that allocates revenue: 30% for Cost of Goods Sold (food & drink), 30% for labor, 30% for overhead (rent, utilities, etc.), and 10% profit, but it's often considered an outdated benchmark due to rising costs, with many modern operators focusing more on prime cost (food + labor) instead. While useful as a basic guide, it's hard to hit today, with average profits often closer to 3-9%, and many operators now track real-time costs and focus on inventory control and labor management for better results.
Most servers agree it's more important that you leave a tip than how you leave a tip. "I don't care as long as I'm tipped appropriately for the service I have given," says server Brandy. Andrea, a bartender, concurs. "I prefer cash tips, but I appreciate any tip regardless of the form."
Tools and Technology to Help
Today's bars often use Point of Sale (POS) systems that make managing tabs easier. These systems can color-code tabs by status, so both staff and customers know if a tab is open or closed.
Paying For Your Drinks
If paying by credit or debit card, you can open a bar tab. The bartender will add your drinks to the tab and charge your card at the end of the night. You can also pay each time you place an order by card or cash.
When visiting pubs in London, many people wonder about payment options, particularly whether cash is accepted. The answer is, yes, the vast majority of London pubs do accept cash payments.
Gen Z is giving up on traditional clubbing due to a mix of factors: the high cost of living, increased availability of at-home entertainment (Netflix, TikTok), a cultural shift towards sobriety/less alcohol, prioritizing mental health/self-care over chaotic nights, and social media making in-person socializing less necessary for validation. They often prefer curated, novel experiences like "soft clubbing" (daytime raves) or finding community in smaller, themed events, rejecting the noisy, anonymous, and expensive environment of old-school clubs.
Companies open themselves up to an increased risk of wage theft with cash payments. Employers paying in cash without proper records increase risk of audits and penalties from IRS or state tax agencies for incorrectly reporting wages. Legal consequences may include fines, back taxes, and interest.
Most places announce if you walk out without paying your tab and they have your card, they automatically add 20 percent. But let's be real, if your not adding 20 percent anyway, you shouldn't be going out for any kind of service.
The Standard Tip: A good rule of thumb is to tip $1-$2 per drink ordered. This applies to beer, wine, and standard mixed drinks. Percentage-Based Tipping: For more expensive cocktails or when running a tab, consider tipping 15-20% of the total bill. This is similar to tipping etiquette in restaurants.
Long story short, everyone—owners and staff—appreciates cash payments and tips over credit cards.” Paul Hamilton, Hamilton Hospitality: “It is more beneficial for both the business and the staff to receive tips in cash.
Four beers can show up on a breathalyzer for several hours, often 6 to 12 hours or longer, depending heavily on individual factors like weight, sex, food intake, metabolism, and the beers' strength; while it might drop below the legal limit in 6-7 hours for some, alcohol can linger for 12+ hours, even into the next day, making it detectable long after you feel sober.
ONE - consume no more than one standard * drink per hour. TWO - consume no more than two standard * drinks per occasion. THREE - never exceed three standard drinks per occasion.
