Went to DD many years ago for IMC course, nice enough sort of chap but wasn't at ease from the start, gave it a day (had booked for 5) and left next day. The whole setup seemed very shoddy ie took over 2 hours get aircraft serviceable to use and getting charts etc out whilst dodging the golfers etc (does he still use the golf club as his office?), wasn't quite my cup of tea. Took over 6 weeks get my money back but at least I got it which I suppose given the reputation flying schools have is a result.
