TIPPING A lot of people dont like to give waiters extra money —— a tip, but maybe those people dont understand about waitresses and waiters. You see, we get very low wages, most of the time less than the minimum wage. We count on the tips as part of income for those that wouldnt get enough money to live. People ask me, "whats a good tip?" I like to get 15% of the bill. So if a customer has to pay 20.00 for her dinner, I like to get about 3.00 for a tip. Sometimes I expect 20% if I did a lot work for the customer. For example, if I got her a special kind of food or recipe from the chef. But do you know something? Very often its the person you work the most for who gives you the smallest tips. But to tell the truth, I do pretty well with tips. Im a friendly person, so people like me. They talk to me during their meal and leave me a good tip. Of course some people prefer a quiet waitress and every once in a while I get some pretty small tips or no tip at all. Once I looked up "tipping" in a dictionary. It said that the letters in the world "tip" stand for "To Insure Promptness". In other words, to make sure that we do things right away. The dictionary said that no one knows if one knows if that is the real meaning of "tip", but it makes sense to me. If we know a regular customer is a good tipper, then we make sure he gets good service. But if someone gives small tips, we arent in a hurry to bring him food or get his drinks. So remember, be nice to your waitress and shell be nice to you.
