I've had people watch and applaud as I race through the store on a handicapped cart, jerking things off the top shelves with the handle of my cane so that they land in the basket.
LMAO! You sound like my "Dad"... he was not able to walk the distance through grocery stores and had to use one of those motorized carts when in stores. He was 6' 3" when he stood up, so even sitting in one of those carts, a big Scotch-Irishman with a cane, yup, he would whip stuff off the shelves with it, too! It was always a riot. And he'd growl at us if we tried to pull it down for him. I think he did it just for the smiles sometimes.
He was also prone to "accidentally" coming close to bumping people with his cart. No, he would never actually ram anyone. He just liked to play, I think. By that point, he was chronically ill, and he was terminal, and he was just taking his giggles wherever they were... and if there was a little kid that wanted to play peek-a-boo with him around their mother's leg in a store, he'd play along. LOL
For me... thankfully I can walk. I came very close to not being able to, but I am too stubborn to accept anything else. And I think I give heart attacks to the store managers when I'm in a grocery store. If it's on the top shelf, I will stand on the lower shelf to reach it... you can see them practically having nightmares of liability lawsuits. They have no way to know that I would never be that foolish... but for me, that's how I get things off the upper shelves of a grocery store. If they can't be jiggered to have staff around, I am not going to spend thirty-five minutes waiting on a staff member. I will climb up, grab it, and continue on my way!
I also used to climb up to our kitchen counters to reach the upper cabinets, before I got hurt. It used to drive my husband batty... he couldn't understand why. Well, he's 5' 8", he has no need to understand it!
