I refuse to tip on anything except things that are traditionally tipped, e.g. haircuts, non–fast food establishments, delivery, etc. I think it’s ridiculous how seemingly everything is expecting a tip now.
But, that being said, when I do tip, I tip exceedingly well. Typically a minimum of 80–100%. I know how much they rely on tips, and I love seeing them smile when they see the tip quantity. :)
Downside is I can’t afford to go those places or do those things very often. But what can you do? ¯*(•_•)*/¯
