Ordering drinks: When the bartender finally gets to you, have your order ready. If you're with friends, find out what each of them is drinking before you even try to get the bartender's attention, then try to put the drinks into some sort of order.
It's usually best to start out with cocktails, move to wines, and finish with beers since cocktails take the most time to make. Wine comes next, taking very little time to pour. Beer comes last so that it has a healthy head on it when the whole round hits the bar.
