I spoke to the manager this morning, and he already knew about this incident - it seems that one of the two employees tattled on himself. To the manager's credit, he was extremely apologetic and told me that they had already been written up. I tried not to make too big a deal out of the whole thing. As a bonus, on the way out, he handed me about $50 of free chemicals! I was really surprised - he didn't need to do that (but it will keep me coming to the store).
