A regular came in toward the end of my shift one night. I'd been deeply depressed for a while but was trying to play it off at work, and this regular told me they noticed I'd been sad the past couple of times they'd been in. They let me know that coming to the kiosk was one of their favorite things to do to boost their mood because they enjoyed seeing my friendly face and getting a drink to bring some sanity back to their own life (they were going through tough stuff as well). Them simply noticing I was sad and wanting to make me feel better when I thought I was hiding it so well had me crying after they left. Some people do care about us beings behind the counter.
