My little metallic blue space-age flashlight wouldn't light. I opened it and found something I didn't recognize. Went to the drugstore where I bought it and asked a smiling, very young cashier what people do with these gadgets.
She opened it up, discovered that the mystery object was in fact a cartridge that holds three batteries. I groaned that they're the only kind I didn't have. She marched over to the battery display that had the AAAs, opened the flashlight, pried out the old batteries and snapped in the new. Since I tend to put batteries in upside down, I was impressed with her savvy--right side up first time!
I thanked, her. I paid.
Then I did the next very important thing. I marched over to the person with the necktie.
Are you the manager?
I told him I absolutely had to have praise for the young cashier put in her file.
He assured me that he always does that, since I'm not the first to see how great she is with customers and with problems.
Moral: In troubled moments, I should look for somebody who smiles. THEN look for somebody who can reward the helpful, smiling one.
