The great TP shortage at the outset of the pandemic

A man shopping in a supermarket brought his purchase of two cans of dog food to the checkout counter. The cashier asked, "Sir, do you have a dog?"

"Yes." replied the man.

"Well, where is it?" asked the cashier.

"I left him at home." He answered.

"Sorry," the cashier said, "You can't buy the dog food if I can't see the dog. Those are the rules!"

The next day he returned to the store and brought some cat food to the checkout. "Do you have a cat?" asked the cashier.

"Yes," he said, "but I left him at home."

"Sorry," she said, "If I can't see the cat, I can't sell you the food. Those are the rules!"

The next day the man walked into the store with a brown paper bag. He walked up to the cashier and said, "Here. Put your hand in here."

The cashier put her hand in and said, "It's soft and warm. What is it?"

The man replied, "I'd like three rolls of toilet paper!"
