You mean like in Japan?

> hasn’t been implemented

I’m not going to evangelize what a correct stance on this is, but IMHO tipping is a big, not a feature.

Southern conservative states in the US have much better service than in Japan, because it's authentic and enthusiastic. Other countries service is adequate, but there is always a tinge of resentment and jealousy of us here in the US.

I’ve actually been to Japan, I’m not sure how their service is substantially better than the US. the restaurants I went to you order from a kiosk and get the food yourself. There really is no service to tip for. One restaurant I went to was a mom and pop and there was some service there as they struggled to find forks for us. We tried to tip and they counter tipped and gave us the small beer glasses we were drinking out of.
