Las Vegas happens to be a popular vacation destination for many of my colleagues. I haven't been myself, but from the anecdotal evidence there is an event series common to most of these trips. A certain amount of money is allocated as “fun money,” meaning it will be gambled away. At some point the person wins a big gamble at one of the many tables or machines. At that point, the person starts to feel lucky, and decides to continue gambling with the hope of repeating the big win. Over the course of the vacation, the remaining cash is spent, and the person comes home, having spent all of the “fun money,” and sometimes much more.
