So they were supposed to stay up all day just in case you might have to use the bathroom? What if it was another paying customer? Would you have woken them up as well? This was the airport crew's fault, not the pilots. You can't refuel a plane from inside the plane. Sometimes plane problems come up while you're in air. At least you're safe and everything worked out. I've flown Continental several times and never had any problems. You probably just got unlucky. It happens with EVERY airline sometimes.
