How do I pay for drinks at a bar?

Some bars work on a “pay as you go” system, meaning that once you order a drink, you should take out enough cash to pay for the drinks and put it on the bar or table in front of you. When the drinks are served, the bartender or waitress will collect what you owe. Leave the change on the table. After you have finished your drinks, figure out how much you have spent, then leave a 15 % tip when you leave. If the bar puts all of your drinks on a “tab” or “bill,” then you pay for everything when you leave. Again, do not forget to leave a tip.
