*is ALWAYS prepared.....Discuss with the management what to do BEFORE hand and have their bouncers ready to go....After all, this is YOUR lively-hood and moment in the spotlight....I jumped off stage one night and beat the SCHIT out of a heckler..Next thing I know, I'm tanglin' with half the crowd....SCARY !!!! You simply have it arranged that if a heckler opens his mouth, you raise your arm and point...The bouncer will do his job and the crowd WILL respect you for it...No fuss, no muss.....BE PROFESSIONAL :)
