My shame tactic is to limp over to an abandoned cart with my cane very visible, then shake my head as I put it in a corral. The amount of gulity faces I see driving away warms my heart just a bit.
There isn't one. Goodness is not one thing, and showing compassion or thoughtfulness in one domain is no guarantee that someone isn't a monster in another.
They apologize in situations when it's not even a big deal, like walking past someone in the grocery store aisle who's trying to look at the items on the shelf.
