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."
