I tip 20-25% for good service, as a lifetime service industry worker. Even for sub par service, I will tip something, because of the wage discrepancies. I'm still in the service/ working class, so I'm very, very far from rolling in dough. It would take some pissing in my Cheerios level bullshit for me to not leave any tip in this country, especially these days. People are over worked, over stressed, and under appreciated.

I've taken to the idea that much like required military service, American citizens of all backgrounds should be required to do a year of work In the service industry, minimum. The only exemptions are the same thing that would disqualify you from the military. It would take a lot

There's a whole lot of data on self worth involved, and empathy for others. And for the love of god of you can go out for a thing, tip what you can if the service is decent.
