And another thing...
My name isn't "hey", "chief", or "bro". I get even more frustrated (and creeped out a little, too) when people yell my real name. Do you like random people yelling at you at your job? I don't, either. Don't begin to order something when I'm obviously making a drink or otherwise doing something else besides paying attention to you.
In fact, unless I make direct eye contact with you and ask you what you need, then please keep your drunken mouth shut. You cheap ass can wait an extra minute or two for your Hi-Life. Money or credit card in-hand is enough to tell me that you're ready to order.
