I did however, back in the day, take comps. Best one I ever got was at a high end restaurant I had done slave labor (internship) at right before I deployed. My date was another Sergeant of appropriate gender and rank (female, same rank as me, and very, very pretty).
The owner even comp'ed the wines. All I had to pay was tip and taxes. 60 bucks.
That kind of meal, I'll go out for, others, I'll cook myself. ;)
