Did you attempt to enlighten this guy? A lot of times, these folks don't have a clue about the proper care of the snakes they have. Perhaps a little friendly advice and the offer of your phone number so he could get in touch with you if he had problems may have helped this guys snake out. Who knows, before you know it he might be a regular on the ssnakess forum. I'm not saying you didn't do all this, but you didn't mention it in your post. The best thing we can do for our hobby (in my opinion) is to educate people. This means kids in school, adults, and yes even the occassional reptile owner who is clueless.
