http://www.foxnews.com/food-drink/2018/08/05/mans-cheap-and-rude-tipping-method-goes-viral.html Just because you're a waiter or waitress doesn't mean a guaranteed tip from me. If I get bad service, I will not tip. The thing that really kills me, letting me sit there with an empty glass, or even worse, not keeping the coffee filled at breakfast. If I get good service, I will tip around 15%. If I get great service, I will will tip upwards of 25%. At a place like the waffle house (greasy spoon) I have tipped 100% to the ladies that keep up with the coffee.
