If I am sharing a meal with others, I don’t care if they put their elbows on the table. I do it all the time myself.
I do care if they chew with their mouths open, or slurp things unnecessarily. I shouldn’t be able to hear them masticating. And maybe don’t break out that toothpick while I’m still eating.
But a friend of mine freaks if the fork is placed on the wrong side of the plate, and another can’t tolerate a drink being served in the incorrect glass (juice gets a juice glass, not a regular glass).
According to this article from The Savory, it’s rude to smell your food in Tanzania. I agree with the part about Thailand: it is generally the case that people don’t eat directly from their forks. Also, you really must never turn down a Russian who offers you vodka. If you plan on visiting there and possibly meeting new friends, build up your vodka tolerance before your trip. Trust me.
Do you have any dining etiquette pet peeves?
