It's only the second time it has ever happened to me. I get home and find someone else's purchase in my bag. I bought artichokes (at 50 cents each) and some bargain mayonnaise. There was long hold up at check out. The person ahead of me was using a debit card and the machine did not want to take it... for three tries. So then she wrote a check. She got cash change, and she bought Lotto tickets. The clerk was thoroughly flummoxed.
When I got home I had a package of salad makings in with my artichokes. I don't mind, but imagine how that lady is going to react when she goes to make supper.
Thus once happened to me at Wal*Mart. There was confusion at check out. When I got home I had items I didn't buy in my bags, BUT this time I didn't have everything I bought and paid for. Someone else got those. And it was about forty dollars worth. Oh, my. I never got that straightened out.
So, shopping today was an adventure, or what passes for adventure when you are old.
In my life, I have walked away without my change far more times than I have been short changed. In fact, I have been over-changed from time to time. At times I have accepted my change and walked away without my merchandise. When I was on the other side of the counter, working at the photo counter of a discount store, sometimes people would walk away leaving their wallets or their purses on the counter.
