I've been known to assist a random Munchkin or two at my local Walmart. The top Overflow shelf is a real challenge. Those driving scooters have it worse.
If yo have Walmart+ for delivery, it helps to order those kinds of things. Anything that comes in a container or package of some kind is great for delivery, and you do not have to try and find it or get it off the shelf.
I hate that I can’t get anyone to help me get stuff off of the top shelf at Walmart. If I go looking for an employee, they usually say they don’t work in that department.
But. I know how to get help now! 
One day, there was no one around to help me get something off the top shelf. I looked around and seen one of those rolling ladders that the employees use to get to the top shelf. Well…..I rolled that puppy over to the shelf I wanted and climbed up to get my item. Employees came rounding the aisle telling me I can’t do that!! I said, well maybe someone needs to be in their department to help customers when they need help with items on the top shelf, or put the cheaper 
on the bottom so we can get to it. I got hateful looks. I gave one back!
Whatever!
That is actually why I use a cane.
I moved to a rural area about 15 years ago, and am familiar with that behaviour. We also have agricultural equipment using the roads to go from field-to-field. I don't let it bother me. I'm still driving at a decent pace, and it beats walking or riding a horse. I figure that I might be that person one day, just trying to get to the grocery store and back in one piece.
