So earlier this week I scheduled a lesson with a tennis pro, I've been going to several of his fast feeds, for a time later on in the week. When the day came I was all ready and excited b/c during the fast feeds he has given alot of great advice that has improved my strokes and my game, but about ~1 before the lesson an emergency occured at work and I couldn't make the lesson. I called him and explained that I couldn't make the lesson and if we could reschedule for a later time that day or another day. He simply replied no and that he would have to refer me to another pro b/c I cancelled with such short notice. I understand that I did called to cancel in such a short period of time but I really would like to receive lessons from this pro b/c his advice seems to click more that others. What is the best way of approaching this situation?
