The fuck is wrong with self checkouts? Better than getting stuck in the standard line behind people who look like theyre shopping for the entire year lol
Self checkouts take away jobs -- and people take forever. Sensor doesn't calculate the weight right? Red light! Someone puts their pop into their cart? Red light! Can't find x item's plu? Let me sit here ten minutes trying to find it! This register doesn't take cash? Whoops! Gotta do a different register. Let me play with my kid instead of scanning items -- or text between scanning.
The solution are Express lanes. They were the solution before and still are.
The first two points are the only valid ones here.
Regarding taking away jobs, surely you've noticed how self-checkouts have only started to become common in response to (successful) demands for higher pay and benefits getting out of control? Self-checkouts don't have to be paid a minimum wage that's ridiculously excessive for the actual job they're doing, or be given a whole bunch of work-related benefits.
In regards to people taking forever, the counterargument there is the fact that you can generally fit more self-checkouts in the same amount of space as you could of regular checkouts, which balances this out. If the average shopper needs twice as long on a self-service, but there's four times as many checkouts, the result is still a 50% reduction in waiting time.
The rest of your post is generally taking worst-case scenarios and describing them as if they're an everyday occurance.
