I went to the grocery store today. I got in line behind a lady who had a large order (it was the shortest line). After they rang up and bagged her whole order, she said she needed to also buy a $100.00 gift card. Then she said she wanted to use the $100.00 gift card, which she hadn't paid for, to pay for the grocery order because her son's swim team would get 3% back (or something like that). A manager was called over and after the whole situation was explained again, it was determined the only way she could do what she wanted to do would be to void the entire order, buy the gift card, and RERING THE WHOLE ORDER! This meant that I had to take all of my stuff off the conveyer belt, so they could put all of her stuff back on the conveyor belt. Needless to say, I just moved to a different lane with all of my stuff that I had to put back in my cart.
I was not happy. When the lady said "I bet you hate getting in line behind people like me", I did quietly say, "Yes, I do".
I understand when things happen at the checkout, but I would think you could figure out that you need to pay for a gift card BEFORE YOU WANT TO USE IT!
