First of all being yelled at inside of the simulator can be very disconcerting and frustrating to someone that has never seen it before. I don't understand why sim instructors do this it can absolutely destroy a prospective pilot and make him feel about an inch tall. Second if you fail the checkride anyway you should walk away. How could they impose a 709 ride after the fact? I thought 709 rides where for when you screw up GA or as a pilot already on the line. And third if all this about piedmont is true avoid them like the plague.No sense it possibly destroying your hopes and dreams and hard work just because a sim instructor wants to get macho and see what you do.
