On a trip to KSC, I paused as I left the Launch Control Center to take a photo of the VAB towering over our bus. The security guard hissed at me about a lightning advisory and insisted that I get on the bus without taking the snap.
When I reached my wife, I recounted this, and the guy in the seat behind said, "They can't do that! This is a free country!", and stood up and got off the bus.
So the security guard literally threw him back aboard again!
