Mainlander has no manner?

My observations:

1) They cut in front of me on more than a few occasions.
2) They always sneak into the train's first class section without paying for it.
3) They talk on the phone loudly and walk around like they own the place in a hotel.
4) They use a saucer to eat food on in a buffet inside a hotel.
5) They take off their shoes and put their bare feet on the chair.

What is your experience? And yes, they speak Mandarin and dress like mainlanders.
