I'm a dog trainer at petsmart and each store will be different. A lot of the people at my store care about the reptiles and if they're not sure about something, or a customer wants to know about the snakes, they come and get me.
We keep the temp and humidity right for each species, but if nobody at the store knew anything about them, I can only imagine how bad they would be.
I would take it on a store by store basis.
With dial guages? And housing multiple snakes together? Baby leos on sand? Snakes only a heat bulb for warmth?
All of the stores are setup the same, it doesn't matter where you go. Reptile people who know what's up or not. Animals are kept like crap. End of story.
