Whoa Jess; the sad part about all of this is that I believe you. People are so damned ignorant regarding reptiles, it seriously sickens me.
My friend has a pet store not too far from here, where she mainly sells fish. She branched off into herps and mainly has lizards (lep geckos, a sudanese plated, think that's it for now.) At first she really didn't know what she was doing, but anytime I can, I help her out. I informed her that her BCIs would do better on cypress mulch than on the sand she had; she changed them and they are defonately shedding and generally living better.
To a degree, I know how it is on her end, to have so many things to do in that store that things get forgotten once in awhile. To not have the ability to hire someone because you're barely feeding yourself and your kid for the first few years. BUT, in reality, if someone wants a great successful store, their cleanliness and care for their animals need to come first.
