Stand up comedy show, running the sound desk.
In a long narrow pub, all one room, with staging and backdrop setup at about 1/3 of the way down the room, we are in the big section, the pool table and the group of guys that 'weren't interested in the comedy', were in the small section.
Initially they were barflies in the comedy section, the MC suggested they come sit down and get amongst the fun, "don't know if we want to watch it yet"... yep, we are going to have problems with these guys, quick, someone get them more rum....
They disapeared 10 or so minutes into the show, and played pool, they were quiet, I thought we might have dodged a bullet...
Wrong. They wanted to heckle from the 'safety' of the pool table. The third time, I get up and go to settle them. I walk around the corner, a bloke is standing on a chair, holding a metal barstool above his head, about to throw it through/over the stage curtain at the comic!!!
The next 30 seconds seemed to last for ages.. I grab what I soon found out to be a rather large shoulder, the size you really don't grab unless you really really have to, if your my size that is, and drag him off the chair, he 'accidentally' 'bumped' into a table when he came down.
He didn't appear to like that and all of a sudden I have fists heading towards me..a scuffle ensues, lucky I can duck because according to the locals he "hits like a freight train".
And like every good train... its time to depart, next stop for you buddy... home.
