RE: Gift to instructor?
Lots of good thoughts in this thread, I concur with 'em. I don't instruct for any reward except seeing the student solo. I have seen them pass me up in skills, and that's actually a great feeling!
I give precious little to my club, other than instructing new folks, so I count this as a part of my dues. I also enjoy watching them gain skills, and feeling like I'm a part of that.
To answer the question, yes, students have presented me with gifts, some expensive. I don't feel these are necessary, but I don't feel I need to pass them on to the club, either!
My favorite author wrote, always accept happily the pay given for your work, as reward for your skill and efforts. If a student feels the need to reward my efforts, I feel obliged to accept with thanks. I hope I make it clear at the beginning, though, that no reward is necessary or expected.
My 2ยข worth,
