There are good people out there, while I won't say this is chilary, it was non the less greatly appreciated. I was sitting in a restraunt alone enjoying my Good Friday fish & chips, and when the waitress came by I asked for a refil on the drink and the cheque. The waitress proceeded to inform me that a refil was on its way, but the cheuque had already been covered by another patron, thankfully she gave me his first name. I'm guessing he came in for take-out and payed for my order at the take-out counter, beacuse I didn't see him sitting in the dining room, and he had left by the time I was told that it had been taken care of. I saw the guy on Easter Sunday who I thought was "guilty" and thanked him, and sure enough I was right!
Personally I think it's polite to hold the door for others, and while I prefer to hold the door for a lady do not get offended if she holds a door open for me (assuming she gets there first and it's conveniant). That said I have had women tell me that it's rude & disrespectful to hold doors open for a lady because it demonstrates that I don't think they have the strength to do it themselves, or am instilling the sterotypical behavior that women should be barefoot, pregnanat and in the kitchen! So I've just ignored those women because I'm not doing it for any of those reasons, I'm doing it because its the polite thing to do, and I was at the door first! Thankfully most women just say thank you.
