Computers Don’t Make Mistakes, People Do
With bar coding a standard merchandising practice, some places sometimes forget or intentionally forget to post the unit price on the shelf with each item. Things can be deceiving. Just last week I stopped at a large grocery superstore. Cruising down the aisle I saw olive oil at an unbelievably low price. I even put on my reading glasses to read the tiny sign. Sure enough it was half price. I grabbed a bottle and headed for checkout. After paying for my purchases, I checked my sales receipt only to find that the olive oil did not reflect the shelf price.
Off to the courtesy desk I went. (The name for customer service there was inappropriate.) The woman there took a barcode scanner to verify the price. She then told me that virgin oil doesn’t go on sale, just the others. I asked her to send an employee to check the shelf. Grudgingly she did. When her worker returned, the girl verified the entire order of virgin oil was under the SALE tag. The woman still refused to correct the error. I gave her back the oil in question, told her to refund its price, and get me the one on sale.
Incidentally while waiting, another woman came up to the desk complaining that the grapes she just paid for which were advertised at $1.99 per pound max. four pounds priced out at over 18 bucks for her 4.5 pound bag. Lesson: humans program computers AND machines.
