When our trainer works any of our horse's and they start to act up, when she pushing the training, she will let them go. Let the horse spend the energy, they are doing the work and yes it might be to get out of working or they just might blow up. But I have never seen a 5min bucking fit. Our horse's act crazy, trainer pushes them to work harder. Runing, kicking, throwing there heads, bucking, but they finally, usually takes just a minute and they figure out it ain't doing them any good. Also I would not leave my horse anywhere that I can't watch and be involved in the training. Just my newbie 2 cents best of luck.
