You reminded me of a funny anecdote.

There is this older guy sometimes working the produce area in Kroger, and I was buying produce, he was stocking.

And he asks "You doing ok?" In this... Tone of voice, that had me wondering for a moment if I was. Like, why would you ask that way, in that tone, if I was not stroking out or bleeding from some place I am unaware of.

I have heard him ask other people this way too while shopping. It's just his tone but it actually kind of freaked me out.
