Ah the slow motion early leavers, how we love them. I've only had to leave early once when dependent on a lift home from someone. I attempted to do so quickly and as painlessly for others as possible but was still overcome by shame and hid my face with my scarf. I gave up half time beer at St Marys during the first season there. The rewards are limited and the resultant pressure on my bladder made the last 15 mins an interesting experience. Can we also ban people who stop/stand in doorways (with the death penalty for those who do so in the entrance to the loo) for no apparent reason.
