Wait for my man to come out of the store

Pull into a Sheetz in Raleigh.  Crazy busy.  We just need diesel fuel.  One diesel fuel pump available. There is a Tru Green truck with a trailer in the diesel fuel lane.  After some minutes, I see they are not fueling.  John is waiting patiently with the RV for them  to leave.  Marla and I in the tow vehicle.  I get out and ask the True Green driver "do you see that big RV behind you? He's waiting to fill up" and he says "sorry, I'm waiting for my friend to come out of the store..."   After twenty minutes the friend appears behind the gas station, across the street, leaving MacDonalds.  Brilliant.
