Sorry Flinty but that is not the way to teach initial type ratings. It is poor, lazy and unprofessional. They cost a lot and it should be done properly in as near possible with manufactures terms and procedures.
A recurrent is a different story, the pilots are experienced and can take on board different stuff.
If the person is unhappy with the training they should take it up with the management of the centre with specifics. I did with FSI and got a very good result. If the instructor co pilot does not do what they are paid to do refuse to get in the sim. I did and they will soon sort it out. YOU are paying for that guy to do his job.
They cannot bill you for something if it is not correct, don't be intimidated. They need the business right now not a poor reputation.
