Like LGray said, the best option it to attempt to educate them in a non-confrontational manner. I read a suggestion on a thread with a similar topic not long ago to print off copies of the BP.net care sheet for ball pythons and provide them to the management at the store. Volunteering would be an awesome thing to do and you could maybe inspire one or two other employees to give a crap about the animals in their care while you were there. At the same time you'd be helping those snakes to feel better and hopefully be healthier. Corporate "leadership" at those places, for the most part, could care less. They buy the animals cheap enough that they don't lose much of anything when they die. Disgusting but true, unfortunately. Kudos to you for trying to do the right thing; good luck and hope it works out!
