My husband and I had bought some gadgets for our almost teen-age grandsons and were leaving the store when we realized we didn't have batteries. He stepped over to a counter to get the batteries but couldn't attract the attention of the clerk.
I waited for a little while then said, "I'll get a clerk over here real fast." With that, I pulled out my pocket tape measure and started measuring a large TV set.
Amazingly, a clerk leap-frogged over several pieces of furniture to reach my side in jig time. To his "May I help you?" I said, "Of course. I'll take 8 of those batteries over there."
