He hadn't originally elected to tend bar, it just happened to be the best seat in the house when he had first wandered in over a year ago. None of the occasional regular who wandered through had seemed to object to this change in whatever status quo they had adjusted themselves to and, with time, he had been entrusted with tasks as sophisticated as cleaning glasses and looking after the bottles each of the regulars set aside for themselves.
His status of wandering tourist seemed to be upgraded to bartender when the rent for both his room and the cradle his ship occupied suddenly was covered by the station. He maintained the room and adjacent controls as best he could without making any drastic changes and, when the opportunity merited, brought in something new from the outside for those who were looking for it.
