Saw that a few times at Reggae as well. As Security, we were fortunate to be camped at the top of the "Bowl"-basically an outdoor amphitheater. At the top fence line was the line of Job-Johnnies, and every morning at about 0630-0700, the Honey Truck would come by and clean out all of the shitters, with the coup de gras being a hosedown with some 10% bleach solution. As soon as I heard the vacuum pump start, I would hop out of the tent and start the pot of coffee I'd set up the night before. By the time my first cup was done, the first few Johnnies were clean and I had the urge to "drop some kids off at the pool". A clean duke accomplished, I'd head back to camp to start the day's grease-fix and maybe indulge in a "salad" or two. Being Security at one of the biggest outdoor Reggae concerts definitely had it's benefits!
