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!
But you can tell when a dish isn’t salted just by the smell. I do that often.
Is it supposed to be salted? Is there already enough salt for how that dish is supposed to be? How dare you assume you know better than the chef!!
