First off…credit card/debit cards are often FASTER than cash. I even know some stores with dedicated express express lanes that only take plastic for added speed. Especially since they can often be swiped while the items are still being scanned. At lot better than someone fumbling through their purse or wallet for exact change, or holding up the line after receiving their change to neatly put it all away before allowing the next person to move up. VERY few stores have dedicated baggers anymore, which more than doubles the time per item since it takes more time to bag than it does to scan.

Not to mention…who is counting the items in a cart? Often someone in an express lane of 10 items or less has 2 or 3. Whereas someone in a regular lane almost ALWAYS has more than 10. Often considerably more.

I don’t know whether it is faster overall – that would be a whole other study – but it does feel fairer. I wish more grocery stores would institute this method.
