I definitely would have given it back. I was at a store a couple months ago and found a crab walking across the floor. Since it was at the same small chain I work for, I didn't take it to the counter, I just picked him up and carried him back to his proper tank.
At the store I work at, a combination of the not particularly snake-proof enclosures they provide us for the reptile display combined with a few less-than-competent employees that occasionally get employed there part time, snakes escape far more often than I would like. In fact, a couple weeks ago, someone rediscovered a red-tail boa that escaped a month or so before I started working there that was lucky to be alive after all that time. I still can't get my mind around how they let a snake that size escape as it's normally the pencil-thin corn or a tiny hognose that escape, but I guess it happens...
