@islanddream. You did 5 training dives in a single day? Under PADI? If so, that is a standards violation, and not a small one.
EDIT: Okay, I reread what you said. You stated you did boat, night dives, drift dives, etc. prior. What instructor signed off on your adventure dives? (boat, night, drift, etc.) This is screaming standards violation and I am hoping I'm misunderstanding you.
I read it the same way sounds like the instructor friend just gave them credit for prior dives. If that's the case I would want 3/5 of my money back and I wouldn't recommend that instructor.
