A sweet, older lady came through my line one day, and was distraught because she was a few dollars shy, and couldn't afford her purchase. I felt so bad that I gave her a damage discount (10%) on an item for a tiny spot needing mended. You could barely see the spot, but it was there, so I did the discount, making it affordable for her. She thanked me many times over. It was several months ago, and the ONLY time I've ever done that. I won't do it again, but I don't regret doing it that day.
I’ve done that. I’ve also had items that for whatever reason didn’t ring and I couldn’t find the price so I just handed it to the customer and said “Merry Christmas”. If customers are nice so am I.
