Hmmm. . . . at the rinks I've skated at . . . . .I've observed coaching by levels more than coaching against adults. Saturday morning, our rink has 3 hours of hard core, group figure skating. Dance class, power class, spins & jumps, and then synchro. Almost every coach teaches in these classes. I was 44 years old, and doing it (except synchro) with all the girls. I'd say that every single coach spent time with me. Only one, who was an Olympic level coach, really didn't give me "alot" of advice, but she gave me some too. She really worked with the advanced skaters, for which I am not. In fact, I think alot of the coaches spent more time with me than sometimes their other skaters. Now, I take an adult group class. The coach isn't my coach, but she comes over and spends time with me, pointers, etc. At our other local rink, I know the coaches. I go over there every few months. They all say "hi" at the rink, Facebook friends with some, and are all encouraging. There is one coach who works with about 5 girls, intermediate level. But, she's busy with 5+ girls whenever I go over to that rink. I don't expect her to drop everything and come over to me. Session is over, and I take off my skates and she runs to talk with the parents. They are all working.
Years ago in Atlanta, I had a private coach and wasn't involved in group lessons. The coaches were all nice, but weren't outgoingingly nice. They were teaching others, and I was in my lesson. If I were to fall hard, they'd help. If there was a problem with the ice, they'd help.
Skating isn't a "chatty" sport. Everyone's busy on the ice. I don't take that as being "not liking adults." Just, sometimes, it's coaching ethics to not approach skaters who are already with a private coach. Alot of internal rink conflict seems to happen with "fresh meat" skaters who don't have a coach, or approaching another coach's student.
Some coaches spend alot of money/time to become high level coaches, charge more, and dance cards are already full with the more advanced skaters. That's usually not adults. I have a gold level coach, and she muddles along with me.
