I've been cool guy'd at some shops and treated really well at others.
My worst experiences were with a shop in SF, a shop in PHX (thanks MaGoof), and a shop in Miami. And, Pharmacy Hollywood is just terrible. I can't even express how much I can't stand the dude who I interacted with on the phone.
Sometimes, it is the shop hiring the wrong dude and sometimes it is the shop isn't run well and the cool guy factor starts from the top down.
I've had great experiences at other shops around the world. It doesn't take much to make someone feel included when they visit the shop and when someone does feel included in the local scene it goes a long way. The dudes at Dime, Seasons, Sunday (RIP), Endless Grind, Cardinal, Menu, Attitude (Bremen), Color, Baitshop (my fav, so sad when this place called it quits), etc. are awesome and made me want to support them.
I feel the bar is pretty low as I think most of us go into the "cool" shop wanting to like them.
