It's the organizer's fault too. This is a contest supposed to be a top secret thing only the insiders know but they tried to cover it by slapping a paper that doesn't covered the whole windows. Even worse, those windows are just normal glasses with no tech that make them blurry and stuff, anyone curious that check the windows will know and wondering "what they are doing ?". I know this contest thing is dumb from the start but are they even trying ?
