Grocery store cashiers are required to maintain an RPM (rings per minute) to avoid be disciplined and/or fired. They are also required to maintain an accurate till to avoid being disciplined and/or fired. Counting out 32 dollars in change to maintain an accurate till will wreck the RPM’s.
Maybe the lady could have rolled the change. Then it could have been weighed at the service desk.
She gets her groceries, the cashier keeps his or her job.
Imagine if every customer came in and paid with change.
Chances are this is the only time the cashier will ever have anyone with that much change going through her line. Maybe the only time this YEAR in the stores.
Why not just take the change and move on?
IF this type of transaction goes on regularly, then let the stores devise a fast method for faster checkout.
If Everyone paid in coins, over an extended period, a good manager would change the standard.
But there are so few of them left in the world it is scary.
