I once got told off by a woman in The Netherlands (to were I had immigrated from my native Portugal) for holding the door open for her and had to explain that it wasn't for her, it was because it made me feel good to be helpful and I did it for both men and women (if you've already gone to the trouble of openning the door, might as well keep it open for somebody who is just behind you).

I just found it funny how a cultural habit from somewhere else that wasn't even gender specific got interpreted as macho posturing.
