Loving my new strategy
Went to an ice cream place to get 2 cones. The worker rings me up and the total comes out to about $18. The tablet shows up and asks for a tip. The worker says its going to ask me if I want to leave anything. I then ask her "do you want to give me a discount" she says "no I can't do that" and I finish by saying "yeah then sadly I can't leave anything". She looked very annoyed but it definitely took away that little uncomfortable feeling I get when I put no tip.
