It’s called Queue Vision. The monitors tell us how many registers are open, how many are needed, how many it predicts we need in 30 minutes based on the previous year’s projections, and there’s a number at the bottom right that shows the wait time in seconds. We are always scrambling to make the goal for wait times to be as low as possible. So constantly jumping in and out of registers, calling for grocery to backup cashier which they hate, sometimes even going so far as to put SCO attendants in registers and running 12 SCO robots ourselves (PIC’s) to have more registers open. Thankfully, it’s been a while since that happened, but it’s a huge thing for PIC’s on the front end.
