Hey guys, I'll make this as brief as possible. I am supposed to give a lesson to a student on Thursday nights for 2 hours. I was given advanced notice that the student wouldn't be able to do her lesson that day, then was told she'd be able to do it on Friday. Well its now Friday 8 pm, and the student still is'nt back yet. This isn't the first time shes had to miss a lesson either, its starting to happen more and more. I was thinking about submitting a bill for the 2 hours to her parents anyway because I was told she'd be home and it's a total waste of my time now. The only thing that is stopping me so far is that the parents/family are good friends of mine. I feel like it would it be unethical of me to submit a bill for the no show (even though thats not my problem) since I didn't exactly render the service I was hired to do.
