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."
