You're leading a group of business people in the Arizona desert. Their agenda is team-building. Today's plan includes rappelling practice.
Charlie was a reluctant participant. He doesn't like exposure, nor does he relish camping. He thinks water skiing on Lake Mead is a better bonding environment. It took cajoling from his co-workers to get him on the rappel. Charlie is now 15’ below the lip and looks awful. The bantering that pushed him over the edge pushed him over the edge. He's red, sweating, breathing hard, and says he is going to pass out. You engage the belay line and try to get him to release his brake hand death grip. This triggers drama, invectives, and a two-handed grip on the main line above his friction device. Eventually he lets go and you lower him to the ground.
