We are loosening point here. It is not a discussion about general store. When I walk into the McDonalds I almost certain that the sales person there would be the dummies in the town. Almost the same thing with many other stores as well as car dealers. When I start ask questions, the simplest ones, no sales clerk knows what to tell me. You are lucky, when they know where to find that particular item on the shelf. It's just the reality of life. Good service happens too, occasionally. I've got used to it. No problem. They want to sell, not to help.
But this is not the point. The key word is - ARROGANCE! They do not want to speak to you? Or God! This is a HOBBY! The nicest part of your life, why do you have to tolerate their behavior? Beginner never asks difficult questions - he just does not know them. The only thing he can ask - which trainer is better, what radio to buy and what engine. That's it. If you do not have time for me - I will understand, just be polite. But as I recall from the beginning of this thread, the vendors of LHS do nothing usually. I've seen them half-sleeping too. The best local hobby shops I've known were more like clubhouses.
I think, it is a good idea to post bad business here. It is the only way we can let them know - they are wrong! I will never, never buy anything from such people, it does not matter - hobby shop or Hobby Sack, Canadian Tire or Sears, even IKEA, any brand. There are some principles in this life, and this is one of them. I work hard for my money. I do not want to finance arrogance. Arrogant people deserve no mercy.

One more thing. I know there are bad customers - their existence is not an excuse for an arrogance. We are not talking here about bad customers, we are talking about BAD BUSSINESES. If you are unhappy business owner with "bad customer" knowledge, please, I am not interested.
