At a previous, early post-deregulation carrier based in a large town in the American Southwest (not Dallas), if you were doing a good job on a sim ride, some check airman might play "let's see how many red lights we can light up." This would only happen to their "friends" and if you had already passed the ride.
I know one guy who had manual reversion, one engine generator working, the other engine inop, and then the slats/flap were stuck at 1.
Everyone laughed all the way down final.
Now, at the successor to that carrier's successor carrier, every sim session is choreographed to the last iota. Never a surprise. Ever.
