Crickets for corn snakes?? (at Petco)

[Lolo76]

First, let me preface this by saying that our local Petco is a decent one... they don't carry many reptiles (mostly due to restrictions within city limits), but the animals they do have are generally well cared for. Of course I always check out the reptile aisle, and haven't seen anything troublesome until now. Usually they just have a few small colubrids, leopard geckos & beardies - all healthy in appearance with proper housing, and the same goes for their rodents and birds.

Now for my question... when I was at this Petco yesterday getting feeder mice, I went to see what they had in reptiles. They had a (very cute!) baby corn by his/herself, with water and CRICKETS. There were only a few small ones jumping around, but clearly too many to have gotten in there by accident. I've only had BPs thus far, but was under the impression that corn snakes - no matter how small - primarily eat rodents. This one was extremely tiny, although I assume large enough to take a pinky mouse. Right?

If this was a big no-no, I'll tell the salesperson who owns reptiles... she only works the register, so probably doesn't get much time to observe the in-store animals. I've gotten quite friendly with her over the last few years, and I'm sure she would WANT to know if anything's wrong. The floor clerks are semi-clueless about snakes, so I rely on this cashier for most of my questions/concerns. TIA for your replies, since I don't want to say anything if I'm wrong about this.
