del_mo:What 2905luvsbubbles said. Dive shops have distinct personalities. Some aren't very friendly, some are. Find the one that melds best with yours.
I couldn't agree more. I was certified 2 years ago, but was too busy to dive until last June when I went on a trip with my LDS.
There are 4 dive shops in town and my LDS is the only one that I remotely liked. The trip leader from last year was in the process of purchasing the shop and completed it when we returned. If he had not obught the shop, I probably wouldn't still be diving. I was very nervous as a new diver. Not about diving, but about people. My LDS owner makes diving and traveling with his groups very fun.
Since that first trip last June, I've been on 5 more trips with them plus two of my own and I've made ~120 dives.
Finding a shop where you can be yourself, not feel pressured to comstantly spend money, and can enjoy yourself will make diving much more enjoyable for you.
