As a relative nubee that close to solo I would not call an instructor pathetic when they are available, and willing to instruct you even when it cuts into their flying time. I have been training with 3 different instructors and each and everyone has provided good instruction. The different instruction methods and view points from each has been more than helpful. It is however a two way street. If you commit to be at the field at a certain time BE THERE AND READY TO FLY. Don' go to the field unprepared. I also don't expect my instructors to fly with me back to back to back. Instead I will often tell them that I need a break even if I don't, giving them time to fly their own stuff or sit and BS or what ever. Trainer nights are the only exception, because that is the time that is set aside for me. The bottom line is instructors are volunteers and should be commended for their commitment to the hobby!
