I, unfortunately, know several rude people. I’m just a beginner and visited many dive shops looking for my OW class. I ran across vary arrogent and just rude people. I met some that didn’t listen to my comments an would try to get me to spend tons of money instead of showing me the entry level stuff I asked for. I am slowly upgrading my equipment as needed, but I certainly don’t need the $700 BCD setup to find out if I like diving. I was told "in case I want to cave dive" blah blah... Well several years later I still don’t desire cave diving. All I want is to get treated nicely and don’t get snotty if I say I’m looking for entry level stuff. As I said, I know of stores in Columbus Ohio I won’t buy from.
