I had to do some shopping yesterday, just a quick stop and a very small purchase. After ringing up the sale, the cashier put my items in a bag and asked for the money. I paid her and, saying I didn't need a bag, put my handful of stuff in my handbag. The cashier promptly crumpled up the fresh plastic bag and threw it out.
I stood there for a split second, then said incredulously,
"Did you really just do that? Did you really just throw away that perfectly good bag?"
She stammered, "Oh, um, did I?" and proceeded to make up some cockamamie story about how some customers won't take previously used bags. At this point, the cashier at the next register joined in and asked just as incredulously, "Seriously? Someone wouldn't take a used bag?" At this point, now committed to her hastily made-up defense, the first cashier stood firm that yes, some people won't take a used bag. The second cashier looked at her like she was plainly crazy.
Instead of pointing out that the bag had hardly been used, I just left. I know she was embarrassed and that pressing the point would only have made her feel worse.
Hopefully, she'll think twice next time about tossing away plastic bags. At least, in front of the customers, that is.
