I'm afraid I might have started that. A guy in homebuilt parking fired up on his own at about 7:58PM and started taxiing out. By the time I caught up to him and explained the error of his ways it was 7:59PM. He didn't believe me (I'm just an EAA volunteer after all) so I advised him to call the tower and get it from them. Well, I didn't hear the other side of that conversation, but the tower allowed him to go. Problem is, after that it became monkey see, monkey do. "Hey, that RV just took off, so I can to!"
The next day we got a small earful from the tower guys and the message in no uncertain terms that this would be the first and last time for this!
(Good thing we get paid time and 1/2 after 8PM.)
