@rxantos - If you think gas station owners are pocketing that much off of self-service gasoline, you should try opening your own store. The profits you imagine go to corporations and investors, not station owners. When I was an attendant, we charged extra for full service unless the driver was handicapped (or a certain elderly lady who felt entitled but cheap and liked to complain to the owner). The gas had an extremely slim mark up on it, as there is plenty of competition in most neighborhoods. Most gas station profit is made off of soda, beer, snacks & the service station. (Just like most movie theaters make money off of concessions, and not the box office.)
Self checkout = Getting rid of jobs by doing the work yourself without being paid.
As for the naive enough to believe that they will save money..
Gas stations where full service. They changed to self-service, getting rid of jobs in the process. Did it change your cost? No. It just increased the profit of the Gas station owner. And, since the Gas owner could pay more, the oil companies took notice and increased price.
So, if you want to increase unemployment. Continue doing your self-checkout, and while at it, why not order On-line.
Bear in mind that less jobs = less people with money to buy products. Which in turn means worse economy. Money is the blood stream of an economy. We have a long term Hemorrhage. And people still wonder why things are bad.
