Here's my take on resumes - they don't hurt in most cases.
I train bartenders in my city and I suggest they bring a resume and/or
business card to every bar they apply with.
Reasons for a resume: First, a resume shows you are serious, you are
professional and you have an eye for detail. Second, many managers may not
have applications handy or they may be too busy to deal with you filling one
out. Plus, if you provide a resume while everyone else simply fills out an
application, in most cases you will standout (which is a good thing). With a
resume you also get to control the information presented to the potential
employer. Also, corporate ownership (hotels, chain restaurants, etc.) like
paperwork and tend to like resumes.
Reasons for the business card: Very good for new bartenders who have very
little experience to fill up a resume. Also, a business card is easy to accept
(also easy to lose). However, as you give it to the manager (never mess with
another bartender behind the bar about a job. My daddy taught me to never
accept a "no" from a person who doesn't have the power to give you a "yes")
tell the manager to stick your card on his desk. Tell him that the next time
he is short a bartender (one doesn't show up, he fires one, gets really busy,
etc.) that you are only a phone call away. They will like that and will keep
your card handy. Plus, if you are new to bartending, the card gives the
impression you have more experience than you may really have. Also, cards are
a good way to get private gigs. Every good bartender should be looking for
private parties etc. to do. Around here a 4 hour party will net you $100-$300.
As for what to put on a resume: Keep it brief. Bar managers don't want to read
your life story. If you haven't worked for many bars, then list your qualities
and such first. An employer doesn't care you worked for Wal-Mart, but he does
care if you emphasize customer service, late hours and a perfect attendance.
One page is plenty!
Hope this helps.
