that sucks, i usually have a couple of mates on hand who always chill at the decks with me so if anyone gets close with drinks they take care of them. Nothing more frustrating then some drunk dickhead doing something like that, which is why i charged so much when i used to do mobile. silver lining, if you were thinking about upgrading now might be a good excuse, specially with all the after xmas sales, and in a couple of weeks all the superstar djs who got shit for xmas and figure out it takes a bit more than just pushing the play button or slamming the cross fader will be selling their stuff
