A man walks into a supermarket. He grabs a bag of dog food, and brings it to the checkout. The cashier says: “sorry, according to store policy you need to bring your pet with you if you want to buy food” The man, who doesn’t have his dog with him walks away angrily.

The next day he comes back and takes a bag of cat food, once again the cashier points out he need to bring his cat with him to buy the cat food.

The next day he comes back with a plastic bag. He asks: “could you please stick your hand in the bag?” The cashier does. “what is that?” Asks the cashier. “It feels really warm and weird”

“Yeah I would like to buy a pack of toilet paper”
