Ever skater needs to be treated with respect as they pay their hard earned money to the coach. However many skaters are not doing it for competition but just to learn a new skill or do something they enjoy.
But sometimes it isn't even about skating.
If you have been with a coach for many years, they can become more of a friend than a coach. Sometimes when people are going through rough periods in their life, they look to the lesson to help them work their personal issues and the coach is someone they can talk to.
My coach has always been great for that. She had one student who was going through a really stressful time in his life. The lesson ended up being more a therapy session for him than an actual lesson. But because she has known him for many many years she was quite happy take him for the lesson with it probably being about a 1/4 of the time actual skating.
He still paid for her time, but she understood that is what he needed to help him with his problems. And maybe the result was he got that ear who listened to him when he had no-one else to talk to.
On the other hand, I would probably be concerned with getting a student who from the get go is using the lesson for reasons other than skating and I would feel uncomfortable with that. She had another student who was trying to use skating as a match making service, to the point of asking my coach really personal questions. And then asking her for other people's phone numbers (including myself). It was really creepy.
