A sense of entitlement. The way I understand it somebody then has to hunt them down to check them off the master list. For our last RCL drill we sat in a lounge and chatted with a few other interesting couples. Did not have to carry our vest or stand in the heat and put it on. Maybe they don't know as much as they think they do and are still operating under older an outdated impression of the drills. Regardless, it says a lot about the person... at least show up even if you daydream thru the whole thing.
