My God that's horrible!!! Did you report it to a manger or anything like that?
If you don't mind me asking, where was this PETsMART?
This upsets me greatly because I work at a petsmart, and it's stores like the one you mentioned that gives us such a bad reputation. At my store every beardie get inspected twice a day, and at any sign of illness or injury they are isolated at once, and are taken to the vet within 3 days. Even if one is smaller than the rest, it gets isolated to put on weight and the vet will screen it again for parasites and the like. I don't know, maybe the store I work at is just an exeption to the rule.
I'm not trying to say pet stores are misunderstood or anything, believe me I'm not. Hell, I myself normally won't buy anything from any other pet store than the one I work at. A good pet store is a hard thing to find. I guess I was just lucky enough to find one of those rare stores that places animal care over profits (our vet bills can deffinatley attest to that, lol)
In general I would have to advise not to buy animals from pet stores. The only reason I can justify getting mine from the store I work at is that I am directly involved in their care, I know every detail of how they're cared for at the store and who is providing that care.
