Not security, but at the last one day assembly here a few weeks back, the middle school where it's held has only one driveway for entry and exit. Just one driveway. And the brothers in charge of parking had allowed it to be clogged down to one lane.
So when we got to lunch, of course people wanted to come and go, but there were no brothers on duty for parking. Nobody was there to direct traffic with only one lane for entry and exit. I saw that, and despite my beard, I handed my wife our bags to put in the car, and started directing traffic until it cleared out a little.
Unbelievable.
