Customer: “I just want a 2x4x20, please.”

Me: “Sorry, sir, we don’t stock 2x4x20′s, but I can sell you a couple 10 foot pieces. That still covers the footage if you can make that work.”

Customer: *completely serious* “Ah! No, kid, it doesn’t work like that! What I will do, though, is take two 10 foot pieces.”

Me: “Brilliant idea, sir.”
