#37 10×20 = 20×10
Working at a hardware store, overhear my manager and an older lady’s conversation an aisle over.
Manager: “Can I help you ma’am?”
Lady: “I hope so, you’re all out of my size of air filter!”
Manager:” Which size was that ma’am?”
Lady: “10×20”
Manager: “Let me see here.”
Manager looks around the shelf. “Here you go.” Hands the Lady a 20″x10″ air filter.
Lady: “I said I need 10″x20″!”
Manager keeps quiet, takes back air filter, holds it out in front of him, rotates it 90 degrees, and hands it back to her with a grin.
Lady leaves in silence, with the 20″x10″.
