A customer walked into our store looking for Christmas lights.
I showed her our top brand, but—wanting to make sure each bulb worked—she asked me to take them out of the box and plug them in. I did, and each one lit up.
"Great," she said. I carefully placed the string of lights back in the box.
But as I handed them to her, she looked alarmed. "I don’t want this box," she said abruptly. "It’s been opened."
