The delivery truck is on a route. He will deliver whatever he currently has in the tank. Same goes for farm diesel, it's supposed to be delivered with red dye, but if the tanker was out delivering to other fuel stops and he has enough left over for your delivery, he'll deliver regular diesel #2 and you'll still only get charged for farm diesel, providing you applied for the permit. Ethanol loads will deliver wherever they can till the tanker is dry, even to places that don't require ethanol. This is just the way it is, and yes, you do have to accept it.
