I was at the drugstore and noticed a young male cashier staring at the pretty girl in front of me. Her total came to $16.42, and
after handing over a $100 bill, she waited for change. "Here you go," said the cashier, smiling as he returned the proper amount. "Have a great day!"

Now I placed my items on the counter. The tally was $32.79, and I too gave the cashier a $100 bill.

"I'm sorry, Ma'am. We can't accept anything larger than a fifty," he told me, pointing to a sign stating store policy.

"But you just accepted that last girl's hundred," I reasoned.

"I had to," he said. "It had her phone number on it."
