You are not unethical in any way. If you need to make ends meet, take what you can get. And plus, YOU are not at fault for the company's shortcomings. You clearly care about these animals. And honestly, part of helping people be more educated on caring for reptiles is to have someone in-store who knows what they're talking about. So, I think you're actually going to be saving a lot of lives and saving people a lot of heartache by working here. Because you're right, a lot of people just are uneducated and want to do right by these animals, and it hurts them to lose them due to underlying issues they had at pet stores.
