Switch right now there are no hard feelings in this business. I've flown with many instructors like him and usually after 1.5-2.0 hours you can tell they are leachers. When leaving the tarmac if you guys aren't talking about the next step ahead whether it be solo or check ride forget it. And that accompanying you on the tarmac is coplete BS. They are suppose to teach you to pre-flight the airplane on your own by like day 2 or 3. I've noticed there are a LOT of CFI's out there who play this game. They lose students all the time too. A few who don't know anybody stick around with them trying to get their PPL for 2+ years.
