An anecdote I've told before on here....
A former boss would swear like a trooper - the f-word mostly. If I was around when he was swearing he would apologise to me by name. So, I was singled out from the (mainly male) workforce as being uniquely unable to cope with hearing swearwords; maybe he thought I'd melt into a little puddle of shock and embarrassment.
He thought he was being polite. He wasn't. He was showing that he thought I was different to everybody else by dint of being female. If you feel you can't swear in front of me, don't swear in front of anybody.
This, IMO, is what happens with the compliments and door opening. You don't need to do it, I can manage without it. I don't get offended, I usually think the perpetrator is a dear old soul who hasn't quite moved with the times.
BTW - the swearing/apologising stopped when I used it back at him. That was fun.
