When I was in high school, I worked for my aunt and uncle, who owned a collectibles shop. At the time, figurines such as Precious Moments and Hummel were very popular, and their store became one of the more popular area destination for collectible enthusiasts.
Since most of the stuff was breakable and there was stock in the back room of many items, we would get the item from the back and unwrap it for the customer to look at while they were ringing up. Occasionally, a customer would find something that they didn’t like about what they were buying. Often paint was incorrect or maybe they would discover a small chip. They would point out the defect and they’d ask for a different one. Assuming we had more, we were happy to oblige.
