I don't want to tip any wait person today.
Why don't you want to tip?
I've always thought that the custom of tipping is repulsive.
If you got bad service then it is understandable not to tip. But the custom of tipping comes from the wait person not getting enough wages from their boss, they depend on tips to make a living. If you received good service from them, then the right thing to do is show your gratitude by leaving a tip. This could also help to make sure you continue to get good service in the future.
Don't talk to me like that, I chose to do this.
I understand, but I think it's the wrong choice. The custom is to tip when you go to a restaurant, so if you don't plan to do that, then it might be best to not go to the restaurant at all.
