Calling all UKes!

Is there some sort of specific British and/or European convention regarding the holding open of doors? Back home I hold doors open for people of all genders and ages if it's convenient for me and them (but especially if they look like they need the help), but here people seem to be less fond of it. I've had a number of people actually open the other door and go through it rather than go through the door I was holding open for them. It's mostly been young women, but one or two guys have done it too.

So what am I doing wrong here?
