-Walking into a shop and the guy working there is wearing a Fox shirt or a Tapout shirt (it's happened)
-DC shoes all over the fucking place, Billabong, Plan B, basically everything that's already been said.
I dunno, everything has already been said. I live in a really small town in Nova Scotia, Canada, so either I go to my local shop or I drive an hour to go to West 49 (Bigger selection but shitty) and we used to have this shop called Zero Gravity, and they had really shitty boards, clothes, shoes, hardware, and a really unfriendly staff who didn't give a fuck, and half of the workers were girls. I mean, some of the stuff was good but it was basically a 2:5 ratio of good to bad. Now, we have this shop called HAF and it's actually pretty sick. A lot of good brands like Altamont, DVS, Emerica, Vans, and a lot of sick hardware like Krooked boards, Baker boards (Whatever), Alien Workshop, Habitat, Thunder, Bones, Spitfire, all of the likes. The staff consists of like 3 guys, all of which skate and they're really nice guys and we talk about skate videos and shit all of the time.
So I dunno, don't get shitty brands of clothes (Because as sad as it is that's gonna be where most of your profit is coming from) and get good boards and hardware! Good luck brah.
Oh my God the worst thing are a lot of surf stuff. Just, no.
