This is a great habit to get in. I usually will do that as well especially in that sort of environment. If I'm grabbing ready-to-go pre-packaged drinks from a concert bar, I'm just gonna tip a flat couple bucks per drink and not percentage. If I'm getting hand-made cocktails sitting at a bar or ordering table service obviously that's percentage. I think a ton of people in this thread are forgetting that you CAN just choose your tip. Anxiety and fear of getting scowled at by the worker are making people hurry and spam the closest tip button and then complain about it online. You can do what you want. It's your life.
