About time we laid to rest this "bumpy trial lesson which never should have taken place" cobblers and move on isn't it? At least Midiman now knows what weather makes him dickie! You learn something new on every flight so in future when the instructor tells you it will be rough and you might not enjoy it or learn much you might listen to this advice?
There will be many more who pitch up on windy days wishing to fly despite the instructors warnings of turbulence but still Joe Public thinks he knows best..... I get paid the same regardless of whether or not you chunder yer dinner up in a paper bag, the job satisfaction comes from seeing your progress which means I have your best interests at heart so if you do insist on flying when it's rough please have the courtesy not to blow chow all over me eh? Ta!
VFE.
