I got stopped around 2:30 a.m. after they officially finished, but I didn't want to drive thru (no one was manning the post, but their stop sign was there even though they were busy with others that they pulled over).
When I asked for permission like an honest John, she asked me, "Well, we're done but have you had anything to drink", I said "Well, I was at the Rihanna concert". Then she asked, "Did you drink?", and I said, "Yeah, but that was hours ago, yada yada yada" (not true, I had a Manhattan about 40 minutes ago for last call).
She asked me to pull over. I blew twice in the breathalyzer device, and she joked "Sir, that's a high score", and flipped it around to show my 0.00 score. Frankly, I think she was using reverse psychology to guage my reaction as I don't believe that I was 0.00 even though below the limit.
