Post how many languages in which you can say Please and Thank You, including your native language. If you can, please provide which languages and how to phonetically say them so the rest of us can learn!
I spent a fair amount of bopping around Europe in the early Aughts and as a native English speaker, I found everyone appreciating my bad mangled attempts at politeness.
I don't really speak Finnish, so probably someone can expand better, but AFAIK they don't have a word for Please. When I was in Finland I went to a coffee place with a friend, and noticed he said "yksi kahvi" which literally means one coffee, when he got his coffee he said "Kiitos" (thanks), I noticed no one used any recurring word that could mean Please, so I asked my friend and he said something like "They're all being polite, we just don't have a word for please, one could say something like: I would like a coffee, Thanks. But that's just overcomplicated"
