USH has exceptional service for guests because they know that this is one way to outshine Disney. Although, I heard of a story where that sort of service has gone overboard....literally. Someone I know who worked the Simpsons Ride mentioned how many guests (Most likely the foreign tourists), will get TERRIFIED when the ride starts. I've heard several reports of them jump out of the ride vehicle while the car is going up out of fear and land on the hidden platform above the loading room. In turn of their stupid thinking, they get a free drink voucher after they E-stopped the ride.
As for the Disney service, I think they're mentality is, "We're Disney. Deal with it."
