“It’s actually a lot more efficient IF people follow the arrows.”
Nope. I go to the store to get 3-4 items. I don’t need to walk every single aisle, not do I need to walk the entire length of the aisle.
BTW, I spent decades on military bases including being a military brat and 25 years of duty.
It wasn’t meant for 3-4 items. And unless everything was in one isle then you were walking at least the length of one isle.
