In the line at the grocery store and a little (like 4 foot 7 little) lady was checking out. Her last item scanned was a rotisserie chicken. She handed the cashier her money, it was counted and the cashier said, "I'm sorry, this isn't quite enough." Before even the words, "I'm sorry, I won't be able to get it," came out of her mouth, the man next to her in line (a very big guy who looked like a mature Sinbad) said, "Let me get that, ma'am."
"No, no, that's okay," she said.
