Tipping culture is uniquely American and a few smaller countries. But the vast majority of the developed world do not tip. It just isn't a thing. In Germany the norm was no tipping at all, except for exemplary service but even then it was on the order of 5%, not trying to gouge you for 30%. It is ridiculous and needs to stop here as well. Just pay people what they are worth, raise prices to cover it, and be done with it. So stupid. It is literally a hold-over from mob-run restaurants during the great depression who stopped paying workers and "encouraged", in a mobster sort of way, their customers to tip instead so they could keep their doors open when everyone else were shutting down. Soon everyone saw this could be done everywhere and exceptions were added to minimum wage laws when those became a thing. It's stupid and yet another place we lag behind the rest of the developed world.
