All. The.Time. I'm not even rewarded for the things that I do. I get to see people happy for a moment, and then they treat me like I don't exist anymore. But when they need me again, suddenly I exist. This happened ever since I entered university. EVERYTHING I did, I never got paid nor rewarded for it. Things like doing their homework, helping them during exams (basically cheating), doing their projects for them, working alone when it's supposed to be a group work, finding that one book for them, LENDING that one book for them because they don't want to pay for it, and then return it to me (thankfully they did), helping them out with computer issues (both software and hardware), among other things. It reached a point where I got contacted by people I barely even met. But yea, I'm one of those people who focus on secondary tasks far more than on the primary ones.
