My boyfriend and I did this by accident in one of the big ass multi floor arcades in Akihabara. By default, service in Japan is so polite, and people are often very indirect, so the employees kept giving us subtle cues to leave that we were both oblivious to. Eventually, we caught on and were like, “Oh shit,” so we headed to the exit. Most of the employees had gathered to wave off customers as they left, but they all looked pretty pissed. We were the last two customers in the building, and they closed the doors behind us.
I still feel so horrible. It doesn’t help being foreigners and falling right into bad stereotypes 😭
