i have done a few now, take $6000 worth of gear let me ask you, how big are you? because i may be 6 foot but im 1 skinny motherfucker, and i dont have the biggest muscles so its hard to tell a 7 foot rock to fuck off just gotta do it with your best interests at hand, i meen id take a punch to the eye over someone pouring a drink on my gear anyday....wouldnt you? so i if they are being a fuckwit i just try keep them away from the gear....if someone is leaning over my table towards me for a request i tend to grab there shoulder and pull them to 1 side of the table and they get the idea to walk around... and as for reading the crowd, (in my town at least) what ive found is all they want is Pop/Charts, and well known House n electro...other then that...nup dont wanna here it
