I work at the local mall. The other day a customer returned to our mobile phone kiosk with a cellular phone she had recently purchased.
She complained that “the phone worked fine for the first two days and then suddenly went dead.”
I asked her how long she had charged the battery for.
She replied, “What do you mean, ‘charge the battery’?”
Upon further interrogation it became clear that she thought the one-year warranty on the battery meant it would last that long.
