Has anyone else tried the self-checkout systems at Wal-Mart? These are systems where you scan items yourself, then put them in the bag. The system compares the weight of the item in the bag with what the system has on record. If the correct weight doesn’t go in the bag in the correct amount of time, the system flips out.
I have a love/hate relationship with them. I first tried to use them on a full load of groceries, and it was a nightmare. The machine called over a cashier for tech support seven times. It complained about everything. At one point, I scanned something, then had to replace the bag because it was full. The system took the huge weight variation of the full bag being removed as evidence that I was trying to rip them off…
I remember a K-Mart in town tried them, then had to pull them out. They had to devote a full-time cashier to watch over them, and I suppose so few people used them that it was worse than a one-to-one relationship between customers and employees. They were removed.
I’ve since come to understand that they’re good on small loads, when you just want to get out in a hurry. And they’re not good for lots of small items (trying to run baby food through them is like trying to herd cats).
