Sounds like you got a year on him on earth but y’all are both still 16. I worked service industry. I consider myself a fuckin great tipper, and every once and a while I’ll even tip 10%.

All depends on the service tbh, but occasionally I just don’t have it or it’s inconvenient to break a much larger bill. I do go out of my way to make sure it’s 20% for decent service, but often tip 50 or even 100% for Fucking Excellent service. It’s totally situational, I am conscious of the persons workload, time of day, etc etc… If they’re lazy pieces of shit, I’m sorry you are not getting the full amt.

So, just realize there are layers to tipping- as there should be. I’d be more worried about him not being able to calmly communicate with you, but that’s just me. Same with you, so there ya go.
