In my experience usually there is 10+ self checkout lines of which maybe half of them are open, only 2 accept cash and the line for self checkout is 3x longer coupled with the fact that people take roughly 10-15secs per item + 10-15secs to find the “finish and pay” button, 15-20secs to pull out their card, or phone, 5-6 secs to get the receipt and leave. If there is a single elderly person on the line or somebody buying an item that needs the employee “blessing” then then that time might reach the full minute.
