I mostly agree with you, except, being one of the people who sometimes asks you for help (but not just because I didn't do my own work), maybe sometimes you just explain things better than they were explained in class. Maybe some of us just don't understand things quite as well as you do, so we ask you, knowing you'll be able to help.
The note copying is a little silly though, especially when the person was in class. I might be able to understand if they just spaced out for a minute or two and missed a few things, but having to copy an entire day's notes is ridiculous.
