The last time I flew FRA-EWR, this almost was the case. I was waiting in the Tower Lounge after coming in from DUS and was called up to the desk. The agent told me that if I wanted the upgrade, I would have last choice of the meals and might not get what I wanted as they would not be able to load the proper catering. I accepted and got a seat in Row 1 and was able to get everything I wanted. Of course, YMMV.
