Chivalry. Hello?!!

[ChiHummer3]

It is sad, isn't it? I get SO mad when people do that. Men or women....but with men I find it particularly rude. I guess I grew up in a family where the man holds the door, and pulls out the chair - blah, blah, blah......but even if that wasn't the case, isn't it just common courtesy to say THANK YOU when someone does you a favor......which is basically what you're doing when you waste that second or two of your life holding that door for some other shmo.
It makes me nuts when people assume it's your freaking job to hold the door for them!!!
