When I was a young lad (once upon a time) I worked for a chain pet store I thought it would be a fun job I like all animals. I tried to learn about all the different ones that we had and what they needed to be kept healthy. When I pointed out that X needed this and that needed y. I was told it cost too much and shut up and do my job. I got in a bit heated argument about ethics with the chain owner, store owner, and sales director (from the head office) as well as my manager. I quite before they could fire me. It isn't surprising that this happens some floor people will know and be good that animals in their care will be well looked after. So it is a job that is easy and don't care at all. The real problem is with managers and or owners. Some care about health and have ethics and some care about money and if it costs profit margins to keep animals healthy or to treat sick ones well the dollar wins. I often go in a check store before I buy ask basic questions like temps for this and that. See if animals have clean enclosures ect. Then I'll check back and get a new clerk and start again if I don't like what I see I will NEVER buy from them. I often will send a letter to owner telling them my feelings and why. It doesn't change anything (or hasn't yet) but I feel better.
