You’re saying there are Costco checkers who can regularly process an order in well less than a minute?
I’ve been going to Costco (originally Price Club) for over 20 years and I’ve never seen one who can do anywhere close to that.
If that were true, they’d never have lines at the checkout counters.
Where did I say less than a minute?
And Costco wasn’t “originally Price Club.”
The founder of Costco was the brains behind Price Club, but he left and founded Costco, then subsequently bought out the slowly failing Price Club.
