Err, sorry.. what do they do that is so rude?

I dont get out much, but when I do.. all the Swiss people I see around here always say hello, and the people on the trains always ask if the seat across fro me is free before sitting down, and then say goodbye and smile when they get off the train, and happily/friendlily answer my questions in English when I'm confused about something..

I guess I find the older ones to be rude, but they are the same in Australia - one lady kept reversing her little bike (one of those motorized ones they ride around shopping centres in) into me at the registers until I moved without saying a word to me - just glaring.

As I said, I dont get out much. Maybe its different if you have to work with them or something.. but I really can't figure out why people on here are always whinging about the Swiss..
