Well established Aero Club I know of is currently suffering due to well-established animosity between current president (long-time preening C185 pilot) and the past president (who is the CFI and 3,500 hour ATPL holder).
Current president has decided to "help the club out" by volunteering his expertise and his C185 to show tailwheel endorsement candidates the ropes, thereby:
a) minimising the hours flown by the candidates on their tailwheel endorsement training;
b) robbing the club of 5-10 hours of revenue flying; and
c) robbing the instructors (who have all spent their own time and money, to some extent, making sure they are back-seat competent) of their quid pro quo.
What a guy!
