I love all the ritualized behaviour, secret meanings and unexpected taboos - standing up when someone of higher status stands, elaborate rules for serving and eating, tapping the table to thank the server, never refuse a toast from a superior, stuff like that.
Whether it’s about meals or anything else, I’d love to hear about any uncommon politeness standard or similar social behaviour that goes on in your location, culture or restaurant!
Not my culture but if you want to see this kinda stuff, try going to Japan. I exited a restaurant there and the waitress very excitedly went arigatogozaimasu (thank you very much) and made a full 90 degree bow. The service culture or like… I dunno how to describe it, like there’s a certain honor in upholding your job/duty there that is just very different from Denmark (which tbf is very much a polar opposite to Japan when it comes to work culture).
