I agree! You are the customer and this training is the foundation of your flying career. Any poor training, which will result in bad habits, will cost time and money to correct. This is too important an opportunity and you deserve to fly with the best instructor you can find.
My PPL instructor was very good and he went out of his way to share extra knowledge and always made lessons fun. My present IMC instuctor is just fantastic. I can't speak highly enough of him as he goes out of his way each and every lesson to make sure that I understand both what we are doing and why.
Bottom line, speak to the CFI. If you don't get any joy, look for a different school. There are plenty of good instructors who will be more than happy to help you.
