They lose a lot of fuel each time they transfer. And I doubt they cool down with the more inexpensive LIN

LH2 flashes off very easily into a vapor which in turn would have to be vented off into a stack. LOX will also flash off but at about 161 degrees warmer, not quite as cold but it too will have to be vented off, into a separate stack of course. With lightning often in the area when this venting takes place I'd believe they have many hydrogen stack fires. Which are perfectly safe.

LIN= Liquid Nitrogen---320F
LOX=Liquid Oxygen---290F
LH2= Liquid Hydrogen---451F

NASA certainly uses vacuum jacketed piping to fill the rocket tanks but each time they fill requires many gallons of liquid gas to chill *cool down* the piping & on board tanks to bring the systems to the working temps. I'd doubt they actually empty the rocket tanks for a short wait. They likely just top off.
