Yes, that is fun! The other half of the coin is when you get employees that worship you like a god. I think those ones are the caring ones, as they seem to want to learn everything you can teach them.

I do like shooting down the ones that think they are better than me just because they work there and they are the "expert". There was this one employee at Petco that comes to mind.
Their hermit crab enclosure was overly wet, I mean it was really swampy. There was so much water in the substrate that you could pour it like gravy. Anyway, there was the unmistakable smell of rotting flesh emitting from the enclosure. I told an employee and he said they had a new guy that doesn't quite what he was doing yet and he had taken care of the animals the day before. Other cages were screwed up too. He then went and got the "expert". She came over looked and at told him and I that's just the way that hermit crabs smelled. I have never kept hermits before, but I have been around quite a few and I know the smell of rotting flesh, so much so that I can usually tell what kind of animal it is down to class.
I argued with her over it she was having no part of it. Even after I told her who I am and what my credentials are. My friend who is a wildlife educator/science teacher was with me. She has kept hermit crabs and she was even arguing with this pinhead of an employee. I should've asked to see the manager, but I just walked away in disgust. Its a shame she had to hide behind her arrogance to cover up her lack of knowledge and the fact that an employee and ****ed up and they had not fixed the problem.
