Did pre-check at IND during an off-peak time (noonish). Very few people going through any of the security lines. Pre-check had two agents working. One was at the carry-on x-ray machine. The other had the pre-check lanes AND the WTMD entry blocked off. She would let two people through the entry lanes (2 lanes), then block them off again. Then after people placed their items on the moving belt for x-ray, she opened the MD lane, and let people through. Then closed that lane, went back to the entry lanes, and REPEAT ,,, REPEAT … REPEAT … Kinda funny; she really was hustling for so few people.
