Personally, I won't shop at Petco at all because of their very irresponsible policies with small animals; they keep little pets like hamsters, rats, cavies and gerbils all together in cages so that the poor baby girls get knocked up before they even get out of the store. Petsmart has a one-sex-per-store policy to protect their critters and their customers from unwanted litters.

Sounds like you just hit on a bad apple among the Petsmarts. I'd send a letter to the management and complain-- there was no reason for the employee to be so rude.
