BFH,
There was one thing I was thinking about that I should have mentioned in my first post to you. When you a learning to fly at an FBO where you work, you should expect to get bumped from your scheduled flights. The customers need to be taken care of first. That is just part of the way FBO's work, especially if your FBO caters to foreign students who have a fixed time to complete before flying home.
Take Care,
