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!
you’d be surprised to know that in many places there’s no such thing and you either stuff everything in as it comes or pack on the ground
Or you prepare you groceries on the belt before it goes to the cashier and sort it into your bag as it’s being scanned. ¯\_(ツ)_/¯
