You could try to speak to the head/manager of the store and let them know how incredibly substandard that is and how much it bothers you and anybody who knows anything about reptiles. If they seem receptive, go back in a little while to see if they've made improvements. If they don't care or if they haven't changed anything, then perhaps you can see about contacting animal control to have a look and see what they can do to help the poor thing.
