In one sentence, describe what the following article is about:

While you choose, stand away from the bar to indicate that you’re not ready to order. If the bar isn’t very busy, consider talking to the bartender for drink recommendations. If the bar is busy and you don’t know what you want:  Look at the bar menu for cocktail or wine choices. Order a simple well drink, such as a rum and Coke.  Look at the beer taps on the wall and choose one that looks interesting. Once you’re ready to order, stand close to the bar with your hands on the counter. This will indicate that you want to order a drink. Once the bartender is ready, they will approach you and ask you for your order. Never whistle, snap, yell, or wave money at the bartender. Speak loudly and clearly, especially if the bar is crowded. If you’re ordering multiple drinks, order them all at the same time. If the bartender needs clarification on your order, they will say so. When ordering mixed drinks, say the liquor type or brand name first and then what kind of mixer you’d like. For example:  “I would like a rum and Coke, please.” “Two Bacardi and sodas, please.” “I need 1 margarita on the rocks and 2 pints of Guinness. Thank you!” “May I have a glass of your house Chardonnay?” Once the bartender hands you your drinks, they will tell you the total. Make sure you already have your cash or credit card ready. Otherwise, you will waste time rummaging through your pockets or your purse.  If you want to keep ordering drinks, use your credit card to open a tab. Your bartender will add drinks to this tab and charge your card at the end of the night. If you pay with cash, you may not be able to open a tab. Depending on where you live, it may be appropriate or expected to tip your bartender. You can leave a cash tip in the tip jar or write a tip on your credit card receipt.  In the US, you should leave 10%-20% of the bill total as a tip. In the UK, it's not as common to tip at the bar, but it is common to tip at a restaurant. In France, the service charge is included in the bill. In Australia, it's uncommon to tip the bartender. In Brazil, tips are not expected but they are appreciated. Consider tipping 10% of the bill total.

Summary:
Choose your drink. Wait to be noticed. Order your drink. Pay for your drinks. Tip your bartender if appropriate.
