I'm in the final year of my Master's degree (by coursework). So there are some in-class aspects.
One girl missed a class, I am one of three doing the same language, so she emailed me to ask for the notes. My hand-written notes. She wanted me to type them up. I figure, hey, they'll be easier for me to read that way. So I type them up and email her the Word document.
But apparently she can only receive files in pdf format. So I have to convert my notes. I talk to DF, we get it organised. Then she asks me (after the briefest of thank-yous) if I could do the same every week because she doesn't want to have to travel to uni every week. It's an hour-and-a-half round trip for me, so I am not sympathetic.
I explain that it won't be possible for me to do that, and besides, she'd need to get the handouts as well (the professor won't let you have two - he's a bit stingy). "Oh, you can just photocopy them at the library (10c per page), and mail them to me".
I don't know this girl outside of this class. Who asks such things of a stranger?
