Background notes: Bachelors need a place to come and eat, and a place to be away from home which is not work. The type of character and setting is classical and is seen in many variation spanning all media and genres, from the mess hall in Beetle Bailey, the bartenders in Andy Capp and Irma from Garfield, over Clark's Bar in the WildStorm Universe to the bar in Ally McBeal. Food and drinks are associated with a lot of feelings and a place where people meet is a very good setting for stories and jokes.
