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.
My husband stepped over to a counter to get the batteries but couldn't attract the attention of the shop assistant.
I waited for a little while then said "I'll get a clerk over here quickly."
With that, I pulled out my pocket tape measure and started measuring a large TV set.
Amazingly, a shop assistant came rushing out of nowhere to reach my side in record time.
To his "may I help you?" I said - "Of course. I'll take 8 of those batteries over there."
