So, for example:

a) I immediately felt that I should shut up about my petty little life dramas because the poor man was in pain. Then I felt annoyed that I was feeling like that, given that I'd just handed him a bunch of money to sit there and hear about my petty little life.

b) When I got home I immediately googled conditions that might cause someone to have arthritis in their 30s, to try and work out what's wrong with him. He has also complained that his back has hurt on more than one occasion, and I have long suspected that something is up with his health. I spend enough time googling my own maladies, I probably don't need to start worrying about his too.

c) I have been thinking a lot about his hands recently, about how they are beautiful hands and I would really like to touch them. For some reason the thought that his hands might be hurting made this worse. Maybe I could kiss them better. Or... something.
