I almost exclusivity self-checkout for groceries, and it had drastically sped up my checkout time as most people in my area opt to use traditional checkout and the stores are still keeping lots of lanes open (just closing the express lanes). The last 3 times I've used a non-self checkout, each time I was double charged for items or didn't have reduced prices applied and didn't notice because I was bagging.
I use self checkout on the machines that don't weigh what you buy. Those work so well. The kind that have to weigh what you buy are slow and they always have an issue when I put items in bulk on them. Like two cans of beer if I don't set both of them down at once it just breaks down and tells me I have the wrong weight in any configuration.
Totally agree. I forgot about those, as I've only encountered the weighing ones once in the past very long time and it was a mess, I can totally get hate if weighing ones are the only experience with them.
