We rarely buy a TV set, perhaps every twelve years or so. And yet I distinctly remember one trip to Macy's to look over their models. I arrived at the store around 10:30 on a weekday, so there were few people in the store. But while browsing the TVs, mostly showing an old football game, I noticed about four other shoppers browsing near me. I was pleased for Macy's that their electronics prices were good to draw so many weekday morning shoppers.
All at once we heard a message on the PA system, something like: “Trouble on the second floor in casuals!” All the other 'customers' in my department rushed to the escalator, leaving me to shop alone.
