Hmm what can I say, not a lot of good things to say about hosts/hostesses in these replies, that's kind of sad. I think the one piece of advice I would give someone who was thinking of becoming a host/hostess is to think of it as inviting people into YOUR home for a party, you entertain, treat them with respect and attempt to make them feel at HOME in your home. Along with that you also have a responsibility to both the DJ and the venue, you are expected to increase traffic, increase tips to the DJ and the venue. Also every venue is different there are no set in stone rules. Some places will encourage certain behavior that others forbid it is YOUR job to adapt to those standards. The most important aspect is to SERVE the customer, whether that customer is a guest,, the DJ or the venue. One more thing, have fun, if you are not having fun there is no point in expecting others to.
