One thing about these fights on the friends and family circuit is that people start leaving after their friend or family member fights so the curtain jerkers usually play to a much bigger crowd than the main eventers
The floor was completely sold out and there was a lot of standing room only tickets behind the seats so the floor was pretty packed and the first several rows of lower bowl seats were filled too, it was a decent house, but by the time the co-main and main went on there was only about 500 people or maybe even less left in the building
Its just a weird little thing that I only experience at the fights, not at any other sporting events or shows
