Same thing happened to me once when I was learning how to use my embroidery machine. Instructor forgot to write down the last class, the one where you finally learn a little bit about the embroidery machine. She was over an hour late, came in all flustered, no notes, etc. Thought she would just go past the time we were supposed to stop -- but I had another appointment. So I just lost out on that, with no apology or offer to re-do. Needless to say, I felt their attitude -- "got your $, we don't care about you any more". Ask me did I buy my new machine there last year? I don't think so!!!!!!!!!!!!
