Have You Ever Seen a Clock?
I was working retail at the time, and this lady walked in and asked me to tell her when it was a quarter after 10 AM, as she needed to catch a bus. We were slow, so I obliged. 10:15 rolled around and I told her, so she dropped her stuff and ran out to get to the bus.
Five minutes later, she comes back in scowling. She then lectures me on how to tell time. “How much is a quarter? 25 cents! So why would you tell me a quarter after 10:00 is 10:15?? It’s 10:25!!”
