I know what you are talking about NC. I work at a LFS myself and there some people that don't give two cents.
So those people just don't get fish. If they are going to put anything in a bowl, they don't get a fish from us (store policy).
If the customer wants something like a discus and does not have at least a 55 gallon tank (and know a little about discus), they don't get the fish. We are mean sometimes I guess, but we try to convince people to get something more suited for their tank instead of having an unhappy and stunted fish(store policy).
A lot of things (larger fish) are special order. Even oscars are special order since most people in my area think a 10 gallon can hold one. The customers that do want these things are more than happy to wait for one to arrive and love the fact that they are special ordering something haha.
In the end, the employee makes the final decision, but I understand that you have different store policies to follow than myself.
On the other hand, there are great customers that sometimes teach the employees. I may have been keeping fish for almost 2 decades, but there is always something new to learn and there is no way for someone to know everything about every fish.
One of the regulars with a 180 gallon tank taught me how to sex Sewellia lineolata the other day. I would not say it is complicated, but something I never looked up before.
Its always fun to learn something new in the hobby
