I work at a petstore and some of the things people steal is just nuts. When I first started we had a lady steal some bacteria starter for her tank, the $20 bottle. If she asked we could have given her some for free from a filter. Our store is famous for stolen animals, mostly puppies. People will pick them up when we are all busy and walk out. A guy tried to steal 2 cocker puppies but got caught and is now doing jail time. Everyone that has tried has gotten caught so far. Like this little old lady. She stole a puppy and it turned out her daughter was the mastermind behind it all, they had it planned and all, the getaway car and stuff, they got busted a few blocks away when they got pulled over for speeding.
Recently we had an idiot try to steal a coastal carpet python. They are agressive as heck and picky, they only eat tan dwarf hamsters, nothing else. Well it was just me and a coworker and we were both in the back for a couple minutes when a little girl came up and told us. The guy was gone already but we had a good discription of him because he talked to both of us for a few minutes. And lucky for us we have cameras everywhere and caught him reaching into the tank. But the best part of it was that we had all of his info because he sells (well used to sell) us fish all the time. So once we got all the together and searched the social networking sites like myspace, facebook, and such to find his pic and make sure that the name and face matched we called him and told him to either return the snake or we would call the police and let them deal with it. He had a friend bring it in for him.
