(not so) slight hijack:
Why do so few people know how to drive the damn things.
You’ll have an aisle that’s just wide enough for 2 trolleys to pass each other, so what do folks do? They leave their shopping in the middle of the freaking aisle while they wander off to rummage to the back of a mountain of yoghurts just to get 28 days shelf life instead of 26.
The other favourite is when you once again have a lovely wide aisle thats about 3 miles long, but somewhere along it is a choke point made by a couple of dump bins / display stands. So where do folks park their trolley? Yup. I mean come on is your shopping agoraphobic? Does it enjoy being close to some cut price tuna fish?
