I know that Liebling, that people have some difficulties, but it's common sense wisdom to tip when someone is serving you and you're getting everything you can ask for, a thank you should be given, a tip.Do you really think all people can learn math. well? Some people have the problem with math... Did you know what illiteracy is?

Do you tip your hairdresser for cutting, perming or highlighting your hair?

for link... I was like speechless over waiter/waitress´s wage. It makes resturant owner richer.... I would become millionaire if I own resturant and hire waiter/waitress cheaply and let them work hard to have tip from customers. I feel bad for waiter/waitress... I understand why they are not happy over poor tips.
