Yep I've posted about that a couple of times
He actually finished a glass during his break.
During the next break he picked up a new one and sipped.
Then he picked up the empty one at next break and drank his backwash. (tipped it way up).
Then he grabbed the empty one AGAIN, realised it, put it down, and grabbed the full one.
C-Span 1 had it split screen the whole time, it was awesome, lmao.
