gratuity
A favor or gift, usually in the form of money, given in return for service.
The other day Christina and I were out to lunch at a cute little cafe. When the check came I was floored to see that they had added a 20% gratuity to the bill. I can understand when you are hosting a party for dozens of people to require a tip as part of the service fee, but a $35.00 dollar meal for two people, give me a break.
A tip is supposed to be a bonus for exceptional service, not an expected absolute for doing your job. If your job that you are being paid to do is to serve me a meal, why should I pay you extra for that? Especially if you sucked. When did it just become a given that you _have_ to tip?
