Don't know if estonians are more or less polite than peoples in moscow.. but in traffic, are estonians surely more rude, unpolite, stupid and whatever than sweedish. only consolation is that italians are probably very likely worser..
And holding a door open to some old lady.. Better I don't do that. Once I was hold a door for a pregnant women with small kids... Something 1000000000 peoples wanted to use my kindness.. can't let door go too, because peoples are clever they hide them selves behind of little kids.. Don't wanna hit a kid with heavy door.
But mostly I dislike those polite seller mans "hello, can I some how help you"..
