I am the owner and sole employee of a small body care booth at a farmer's market. Our product line has historically been sold mainly door-to-door, by distributing fairly large catalogs with a unique design and appearance. For this reason, we have stacks of these booklets near the entrances and in other public areas, stamped to indicate our location inside the market.
Last week, a customer came in with a catalog turned back to a page offering "buy one deodorant, get one for $0.99". The retail price for these products is $1.99.
I directed her to the deodorant display, and she brought 2 items to the counter. I rang her up for $2.98. She angrily said that the price should have been $1.98, because they were "on sale for $0.99". I explained that the discount was on the second item purchased; the first item was to be rung up at the regular price.
"Well, I don't want the $1.99 ones, I just want to buy the $0.99 ones!" I tried to explain the idea of a BOGO sale, but it just wouldn't sink in, and she continued the argument even after I suggested that she leave the premises.
To my utter delight, she asked me for the owner of the store (after years in food service and retail, it still makes me smile when someone asks me this, especially when they are mad at my behavior), then called me a liar and a fraud and demanded to know the name of my "boss in corporate".
As it happened, our regional sales manager was just then picking up lunch at the BBQ stall next door to my booth, so I said, "See the lady in the [brand] t-shirt over there? That's her. Let's go together so that we can both tell our sides of the story."
For some reason, this caused the customer to lose her nerve, and she peeled away and went out the nearest door.
I wonder if she would have demanded a bagful of free items if we were having a Buy One, Get One Free sale? "I don't want the ones that you have to pay for..."
