A little old lady went to the grocery store and placed the most expensive cat food in her basket. At the checkout, she cheerfully told the cashier, “Only the best for my little kitten.” But the cashier shook her head. “I’m sorry, ma’am. We can’t sell you cat food without proof that you actually own a cat. Some elderly customers buy it for themselves, and management requires verification.”

Annoyed but determined, the old lady went home, fetched her cat, and brought it back. Only then did they sell her the food. The next day, she returned to buy a dozen pricey dog cookies. A different cashier insisted on proof of a dog, explaining that some older people buy dog treats to eat.

Once again, the old lady went home, brought her dog, and finally received her purchase. On the third day, she arrived with a small box with a hole in the lid. She asked the cashier to put her finger through the hole. Alarmed, the cashier refused. “What if you have a snake in there?”

The old lady calmly assured her it was safe. The cashier hesitantly stuck her finger inside, then quickly pulled it out. “That smells like crap!” The old lady smiled proudly. “Good. Now may I buy three rolls of toilet paper?” Never underestimate a little old lady!
