We have a lot of customs and rules when it comes to “eating in a mannered way” here in the western world and I actually don’t know much about it… Like which fork to use to which desert and so on.
Usually it doesn’t matter if you’re not eating with the King or something like that anyway.
Other manners are quite obvious and some are not. For instance, in almost every restaurant in Sweden, we have toothpicks so people can clean their teeths after dinner. I was about to do it once when I was eating with my Peruvian niece and she got so disgusted when I grabbed the toothpick so she looked away. It’s apparantly not accepted in Peru.
Here, this girl explains some eating manners in Japan that are actually modern, so they might be good to know!
