How to be helpful as a pet store employee?

Hi guys! I've been working at a pet store for a little while. I know they aren't ideal but I have to make ends meet. I've been doing my best to help give the hamsters better care whilst in the store (I give them more bedding than I'm supposed to, I sneak them millet sometimes, etc.) and I was wondering if anyone else had ideas on how to make a difference for these little guys! Thanks!
