RANT: door-holding etiquette

yep, this is another complaint that has been inspired by the workplace, but unlike the elevator rant, i think this would still be applicable to any situation.

if im courteous enough to wait and hold the door for you, you should be courteous enough to acknowledge my presence. note that im not looking for a verbal 'thank you' or anything like that. but just a glance in my direction, and maybe a smile or a nod, letting me know that you are somewhat appreciative would be nice. i am not a door stop. or at least i dont think i am. dont get me wrong, im not holding the door just to get recognition. i just think common courtesy is going to shit, and its kind of sad.
