In a flight school environment, I have seen the results of pilots screwing around beyond their or the aircrafts ability. Actually had a renter pilot get a guilty conscience once and confess. He couldn't get to sleep later that evening. He suggested that the aircraft be inspected. Unfortunately, That's not the Norm.
