Things can be a bit rough around ops, BUT the next time it is rough, look at what is causing the problem. I will bet you a nice bottle of authentic Russian Vodka to your cake that the mess is because everyone wants to fly between the hours of 1pm and 5pm local. There simply is not enough airplanes and practice area space for everyone to fly in a 4 hour window, and cross countries just eat up more airplanes, one 2 launch cross country is equal to 3 airplanes being gone.
A lot of students are excited about flying (the ones you refer to as nerds), they are a joy to instruct. The grumpy CFIs to which you refer most likely have the other side of the coin. The student who shows up everyday pissing and moaning about this and that (especially airplane availability) but won't agree to a 6am launch when your pick of airplanes is available.
There are pricks at ops (Leo comes to mind, if he is still there). BUT, if you play by the rules and don't buck the system, and learn to use the system, you should have little discomfort.
