I remember years ago when WiFi in our lecture theatres was new, they'd put the access point in the now surplus projectionist's booth at the back. It would reach the lectern at the front, so those of us needing WiFi for teaching there could set up with connectivity. But then your class would enter, and before you knew it, there'd be a couple of dozen laptops and other WiFi-enabled devices closer to the access point, and poor me at the front would lose connectivity. Of course, any complaints to the powers that be would be investigated with lecture theatre empty, and deemed frivolous!
There's also the fact that bodies (full of water) are rather absorbant in the 2.4GHz band, so when there are a lot of people in the room the signal doesn't go as far.
When I'm setting up wifi for a conference, I take advantage of that to let me deploy more APs (re-using the channels at closer distances than I could normally get away with)
