curb situation

A seemingly mundane, yet ironical occurrence in everyday life that you could imagine being on an episode of HBO's "Curb Your Enthusiasm."

You could also imagine the situation occurring on an episode of Seinfeld.

I had a curb situation today at the craft store today. Here's what happened:

Customer in craft store: "Where are your yardsticks?"
Craft store employee: "We don't sell yardsticks."
Customer: "What? What kind of craft store doesn't sell yardsticks? This is insane!"
