Went to Costco last night around 8pm to grab a couple of things when I thought checkout would be quick. The self-checkout line was unusually long, but walking by it appeared that there were a couple of checkout stations that were open but nobody using them.
Grabbed a couple of things, looked for another I couldn't find, and the line is still long, but there clearly are stations that are open. Turns out there are three Costco employees scanning the items in carts with a hand scanner before people get to self checkout. What is this?
Finally gets to me and I ask what they are doing. Guy says "pre-scanning". What the hell is that? I look at the guy and say, "How does this make the checkout process more efficient? Because there are open stations where people can be checking out right now." He says I don't have to "pre-scan" and can use an open station. "Thank you", and walk right past a couple of people getting "pre-scanned" and check out my two items.
I can assume this is some type of way to reduce retail theft to ensure everything that goes through self-checkout gets scanned and paid for. But if it builds a line while there are stations open, it won't last.
