I pulled up to the drive-thru of a fast-food restaurant and ordered a coffee.
When I placed my order, I asked if they could put some ice cubes into the cup so that I could drink the cool coffee quickly.
At the pick up window, there was an unexpected delay.
Finally, a teenage blonde girl came to the window looking frustrated.
“I’m having a problem”, she announced, “the ice keeps melting”.
