Emob78: I'm just the opposite. I don't go to bars any more, but back when I did, I always preferred the 'last call' time period. Some of the funniest, most interesting bar chats would happen in dark corners while the bartender was cleaning up.
Besides, chances of fights and other weekend warrior silliness was rare when there were only a handful of dedicated booze vampires pounding down their last shots. There's also some primal joy one gets from being the last one to walk himself out of a bar on a Saturday night.
On the contrary last call are the two words I hate to hear. :P
