I think it's fair to assume the target of this meme is not that scenario.

Edit also generally agree

So they were able to get to the cart station before their shopping unassisted, but are unable to return the cart because the walk back is unassisted?

I don't buy it.

So what actual disabled people do is just to talk to the cashier, who will say "oh let me flag down one of the Noble Cart Lads" or "oh just leave it, we'll have someone out in a couple minutes anyways". It's standard to have someone on staff that helps mobility impared (or otherwise disabled) people load their car. If a place has mobility scooters, they absolutely have one of these people too.

What you're doing here is advocating for accommodation on a largely solved problem, without just asking the people you're advocating for about the problem, and trying to signal your virtue while doing it. Stop it.

(The reason for no cart returns next to disabled spaces is that many people will just sorta fling their carts at the returns, creating a whole lot of obstacles right where you least want them.)

If only there was a device they could use to place their walking aid in (assuming they don't need a full on walker) to carry it while their hands are full of shopping cart

If my friend with a CASTED LEG could manage to return their cart then it'd take a disability that means you probably shouldn't be out and about on your own to not return it
