Some times they just can't help being snarky.
KDCA was a big mess one night when fast-moving fog was shutting down a lot of nearby airports and DCA was still above ILS minimums and a lot of planes diverted their way. I was in the line and the guy ahead of me was all over the place when the following exchange took place:
DCA: Nxxxx, do you have an ILS receiver in that airplane?
Nxxx: Roger we have one.
DCA - Could you PLEASE TURN IT ON!
