My In-Laws owned a number of Jewelry stores and I would spend some Saturday's at one visiting my Brother In Law. One day a women came in to complain that an earring my brother in law had fixed for her for free had a little "glue" on it and her husband felt he should replace it with a new set of earrings? My brother in law showed me the "glue" and it was the size of a point on a needle and he told her he could just just remove the glue. She was insistent that he give her a new set of earrings. He asked her if she was going to be in the Mall for awhile and she said yes. He asked her to give him a few minutes and could she come back, she said yes. She came back, he gave her the earring back in a little bag, told her he had returned it to its state when she first brought it in and could she leave her name and address as he would rather not have her return to his store. There were no insults or raised voices just a simple solution to a problem customer.
