When I first started at ATP, everything was fine. I had a good instructor, who cared about his students, and actually showed up on time for lessons. Everything was fine. I had this CFI till my instrument rating. I passed my checkrides in the first try. Then I finished my cross country flights, and gets another CFI for commercial stuff. I knew from the beginning that this guy is going have issues with me. First of all, he dosen't show up on time, sometimes 1-2 hours late, and tells me he didn't see me. Then I get scheduled for ground school for 2 hours, and he teaches for 5 minutes, and just walk away. Don't get me wrong, there are a few CFIs that care, but most don't, and also the management. Also, I've been off for sometimes for 5 days off straight for no apparent reason. I've personally seen some people getting special treatments. I think everything would have been fine if I had the same CFI, but they gave me an idiot for a CFI (you know who you are). Anway, basically I got kicked out for accidently over servicing the engine. When I checked it, it was between 6-8 qts, 7 qts (2000 model seminole), so I put 1 quart to fill it up to 8 qts, but when my CFI shows up to check it, it's over serviced. I don't know if somebody serviced it after me because I finished the preflight 2 hours before the CFI checked it. They gave me a number to call to the main ATP office to talk to somebody over there. This guy was really ignorent, basically he talked like an idiot like he didn't even know about this. I'll never go to ATP for anything, I should've gone to a local FBO.
