First make sure you have supplies. Get some "speed-pourers" - don't have to be stainless, the red plastic will do & they're cheaper! Have a mixing tin & strainer handy for drinks called for straight-up & be sure you have sip-stix so folks can stir their own. Always ice, liquor, mix. With speed-pourers the rule of thumb is a slow 1-2-3 count then add mix sip-stix & send 'em on their way. Bev naps are always a nice touch placed in front of them b4 they order! Don't forget your tip jar unless the host(ess) prefeers you not use one in which case make sure you are paid handsomely
