Not So Helpful

I used the self checkout at Walmart. The barcode didn't work so I used the search option and selected tomatoes on the vine. I scanned more items bit was interrupted by the helpful clerk who said I had not paid for something. I explained about the barcode and search option ending with tomatoes on the vine. She assured !e it said tomatoes on the vine when she did her bit. So I gave up and checked my bill showing her tomatoes on the vine appeared twice rather widely separated. She said to go to customer service to get it straightened out.
