why do certain bars advertise that the act will be onstage at 10 oclock and without any sort of apology the act goes on at 10.30 or thereabouts ?last week i went to see a comedian who was billed to be onstage at 11.30 and at midnight i went to the d.j. and asked him "when will the comedian be on?"he replied"hes not here yet,hes stuck in another club"he was redfaced when i told him"hes been chatting at the bar since 11.30 !!"he eventually went on stage at 12.15.
