I had something like this happen. The clerk kept calling fish by the scientific name like he was very knowledgable. Any way I didn't buy from that store and never did again. I wish I was buying something expensive at the same time so I could of pointed out to a manager that they lost a large sale because of an incompetent employee. They didn't seem to care about just buying a fish. Tell some one with authority why you will not shop there anymore. Just watch for a little bit first and do not buy from any one store right away.
