Sorry rollout - I think you may have misconstrued the purpose of a discovery flight in the most general of terms. It is suly a relaxing, no pressure, little rush, present experience designed to encourage the fascination of fight in a person - not FAM-101 with instruction (Did you pay for an hour of instruction? A discovery flight usually costs less)
If you decide to train there, have a sit down with management (and certainly your assigned CFI) and explain your expectations during training. Hopefully they will be able to match you with an appropriate stylistic CFI. If the school has a good pass rate then they know what they are doing.
Good luck and enjoy the ride if you decide to take the plunge.
