I was checking a woman into the hotel, and she handed me her Visa credit card. Then she asked, "Now, if I want to put the last night on a different card, what would be the best way to go about doing that?"
I had to think about it for a moment, because there are a few ways to go about doing that, and I couldn't remember the best way. In an act of 'pondering, I placed the tip of the edge of the corner of her card to the bottom on my chin, and said "hmm..."
"I'm sorry," she said, "But are you touching my credit card to your germ-y face?"
I was stunned. I looked at her disgusted face, and I removed the tip of the edge of the corner of her card from the bottom of my chin. I said,
"Oh, I'm sorry, I wasn't thinking. Oh... and uh oh... it looks like I accidentally touched it with my filthy fingers, too."
In other words, Go Dig Yourself A Hole.
