Rememder, that while you work alone behind a bar, others like karaoke,dj's and poker dealers can help bring in business for you. It's not easy sometimes to promote yourself, so use some of the others people that cross paths at your job. Let's say you work on Thursday but the band is always scheduled to play on Fridays, it's not your night but just building a relationship with the band members, sometimes can lead to increase traffic on your nights. This occurs with good things being said about you or you are remebered to be working on that night. These relationships can transend to other bartenders also. you promote them and they promote you. Facebook and twitter are ways to keep connected.
