I do the same thing! Except I am not as good at packing things as you are. I love going to my local Publix Supermarket and seeing the looks on the employees face when I allow them to take the groceries out with me.
Same with us, Mr. Paul. Between my wife and I and our 2 scooters with top cases, we can pack in a lot of groceries. We use our top cases, hang big bags on the floorboard hooks between our legs, and also carry a backpack for smaller items. People are always surprised that we can get it all organized and packed into our 2 scooters. It is an art form, for sure.
