When I was younger we had a 8 week choir tour through Japan, Korea, Hong Kong, and China. We were bused and shuttled, dealt (to a much smaller degree) jet lag, lack of sleep, hunger, and by the end of that 8 weeks every single one of us were showing the worst side of our behavior. And this is with far, far less stress then what the race puts on racers (and the stress racers put upon themselves).
Now if this outburst is typical behavior from Dan, then I wouldn't want anything to do with him. But if this is a one time explosion he has (and so far we have seen no evidence of Dan having a temper, really at all), then its unfortunate, my sympathies to the local and hopefully Dan feels bad for his behavior (as we all should when we over react, and I doubt there are many of us who can say we never have).
