It surprises me he was so honest about not putting you in that department for that reason. Most of them would at least lie and say, "There's no position available over there." lol.
When it comes to pet stores, there's always going to be good and bad. That situation in Dallas is not something I've ever come across. When it comes down to it, the big pet stores are paying very little for very crappy work. My pay isn't worth what I have to do everyday, but I need the job, and it's not as bad as other places.
I know my manager prefers to hire people with at least some experience with animals, but sometimes she doesn't get those applicants. She went a while without hiring anyone when we needed another person because she wasn't pleased with the few people who had applied. But truthfully...when I started working, I had no experience with animals. As a child, I had dogs and a rabbit, and that was it. Now I can talk for hours about reptiles and amphibians and fish. So sometimes those uneducated workers learn some things on their own.
I know that in my petstore, when an animal is sick, it's immediately pulled off the floor and taken care of. If it is something more than just a broken tail on a lizard or bit wounds, etc, it's taken to the vet. I've never seen my managers express a problem with that.
So...in summary...each individual pet store is different, if you know what to look for you can easily spot which ones to stay away from, the situation in Dallas sucks (I hope you at least got a job soon after somewhere else!), and I didn't read all of Deku's posts because it made me think of some of my annoying customers, and I truly don't wish to think about them. :P
