For the record, I rarely go places where I have to use a buggy that doesn't have someone push the buggy for me out to my car. I didn't like having someone push my buggy for me, till my wife pointed out that they were "special" folks. And, everyone had to have them push the buggies. Not like they thought hat I was too old, ha ha.
But, yeh... I would put my buggy up too, at least if they gave me corral to put it in, but I'm not taking it all the way back in.
It is just the social media shaming that goes with it, like tip shaming. To say that there is no reward is silly, this whole thread is a big pat on the back reward.
