Can just be a matter of the the individuals too. I've been into the same shop in my area and one day I get snubbed and the next I get great service (off season so they're not too busy or anything). If you get consistently snubbed at one shop, try a different one. There are shops that cater to all kinds of different people (and a few really big shops that try to cater to everyone). Once you find a good shop, stick with them, that relationship will make you feel more comfortable and give them a regular customer.
