it was on the right side by the priority immigration desk, they set up a cornered area with those retractable belts used to queue, felt like a chicken pen, separated only by a not so high wall were the officers had desks and computers behind us, I was being questioned coming in as well, I'm not sure of each persons exact situation but they were verbally telling people while filling in forms that they won't be allowed in, and the kept repeating the same reason, didn't matter the person's nationality, they were questioning everyones reason for using the visa exemption, kept saying you need proof of accommodation for your entire trip, 10k baht, and return ticket, telling people that you can only use the visa exemption for 90 days every 6 months, this is what happened, I was held there for 6 hours, they were denying people entry, or telling people to get the correct visa and try again
