Of course I do. In fact I do it so much I think its gone from politeness to a compulsion. I'll hold the door open for the people behind me, and the people behind then, ad infinitum and I'll often be stuck holding the door for quite a while. I hold it open it for people going in or coming out, close by, far away, Men, women it doesn't matter, I'll hold the door open for them.
I think it's because I'm addicted to praise. I grow happy when people say thank you, and sad when they do not.
Maybe I need professional help...
