Get back in your disability hole. You don't deserve to be seen in public. Order online and we'll throw the shittiest scraps of produce on the shelf down there for you if you don't want to be sneered at (which you deserve for being disabled and possibly even faking it)
What the fuck is wrong with these down-punching reactionary service workers? You're the very bottom of a mountain of shit rolling downhill so you need to create a class to abuse beneath you? Yes they are in fact entitled to access to fucking groceries.
And the carts have that safety feature which causes them to instantly stop if there's no pressure on the seat, so every time the rider hits a bump the cart suddenly stops and doesn't restart unless the rider, who probably cannot stand up unaided, has to get up and sit back down again. Not that the cart's interface explains that's what happened, so the end user has to sit there and assume the cart just died for no reason.
The carts are such a non issue. Besides, if they were doing their jobs properly they’d be using the management supplied raincoats to get them if it starts raining (preferably before).
For the record, I work retail and am allowed to say that. This isn’t somebody punching down, it’s sideways.
