Hosts are in a position to get in the way. I was a supervisor when I had a real job. I figured out it was my duty to make those who worked for me successful in their jobs, and sometimes all that meant was to get out of their way and let them shine on their own. While a host doesn't supervise people, he does supervise the venue, and I believe the best ones try to make the guests successful so everyone has a great time.

Now, I'm off to mull over the concept of a 'rostafarian'.
