People have to go to both the toilet and the bar--so the act that sends people to both of these places actually fills as important function as the act that rivets them to their seats.

I am reminded that, in the days that movie theatres showed short subjects and cartoons along with their features, it was common practice to show something uninteresting after the feature, to clear the theatre.

I suspect that some of the groups that I've played with were booked chiefly on this theory.
