Customer: “Is there an elevator to the theatre?”

Me: “Yes, directly across from me.”

(The customer walks to the front of elevator and starts yelling…)

Customer: “How does this thing work?!”

Me: “Press the button and when the doors open, get in and press floor number 2.”

Customer: “No, how does this thing work?”

Me: “Do you mean the physics behind elevators? This brand of elevator…or something more specific?”

Customer: “No, how does it work with me?”

(My phone is ringing and I must go answer it in a different room. I wander off. Ten minutes later, customer is still arguing with elevator. I leave for lunch…a very long lunch.)
