Please and thank you, plus holding doors for people seem to be fairly passé here in the US. I do these, but a lot of people don't. Where I used to live (in Los Angeles) people were just downright rude. I could hold a door for someone and not get a "thank you". I say "you're welcome", anyway. Maybe they'll get it, who knows.
If you get to thinking you’re a person of some influence, try ordering somebody else’s dog around.
