Many years ago, I had a summer student job. I worked at a Hardware store that sent out a national weekly sales flyer. However the store was in our small town and wasn’t your typical big box store. Customers would come in to purchase an item that was highlighted in the flyer and we’d only have a few before being sold out. The manager would give a rain check and the customer would be called to return to purchase the item when it came back in Stock. Never a fuss from anyone, it was what it was… Actually a very personal experience that is sadly missing today.
