Zip code RANT !!!!!!

Probably just me but i'm having a hard time with this one. Maybe i'm missing something very simple and if so clue me in. Maybe i need a book with a lot of info that i don't have. People post an add for a part for sale or maybe a part needed. There is no location under their name there on the left but they do find the prescious time to post a zip code. Now, if i am more into seein this guy gets the part he's wanting more so than he is wanting it, i'll take some of my valuable time and go to his profile and maybe find a zip code they so generously stuck in there for us all. OK i now have the zip and it maybe more simple for me to go somewhere and look up where this guy is than it would be for them to post their real location. I have a lot of parts and love to help those that like to help themselves but when they make me start working right out of the gate on something they need, count me out. The parts can stay right where they are. Is it a fear thing? If you are selling something and you don't post your location i don't need it. This is a hobby, not a job for me. O.K i've taken some pills and feel better now. You guys are great. Now all i have to do is straighten your asses out. Wish me luck. Man , I feel better already.....
