bartending
as described within this paper, there is much more going on behind the occupation of the bartender as one may have originally thought. The stereotypes of flair bartenders and the knowledgeable advice givers that the bartenders are perceived by are mistaken due to present knowledge of the duties and responsibilities of the bartender. So the next time you order a drink at the bar, remember that the person serving you that drink is concerned and responsible with much more currently going on in the bar, then in serving you that drink. So drink up, thank the man who served you that drink and contributed to your alcohol intake, and most importantly always remember to tip well.
