Just to be fair . . . from what I see here, I'd guess that at least 1 pool store in 50 provides accurate testing and generally reliable advice. It might even be 1 store in 20.

So, not all pool stores are bad. The problem is, the only way to know whether you can trust yours, is to learn enough so you don't need them much, even if they ARE trustworthy!
