Just don't grab my cart and pull it to another aisle. Or don't grab my cart to take my items from one checkout line to another.
Just DON'T GRAB MY CART!
Why? I am disabled, and use the cart in place of a walker while in grocery stores!
Once you grab my cart, you leave me with no support. There I am, with nothing to balance, trying to catch up to my groceries
You wouldn't grab away a disabled person's cane, or walker, or would you? It is the same thing when you tear away a grocery basket an elderly/disabled customer is using for support. I usually put my cane in the cart while depending on the cart for support. If you just come up and grab my cart, you leave me helpless, without the cart or my cane for support!
I know this situation would appear humorous to some, but its really NOT funny and could result in a serious accident. Of course, the store that "cares" so much about the customer could also face something they really "care" about, ie lawsuit
But how are the poor employees supposed to know? Well, that's why you politely ASK before doing something. You don't just assume what you're doing is ok.
