within reason. if there aren't even enough lights to prevent a trip and fall, which there are not btw, then you bear responsibility. and anyone who has ever gone to a DS game has noticed the "security" that is omnipresent prior to games is nowhere to be seen after. maybe its always been that way but its really no excuse. guarantee if that was a family member of yours you feel differently esp knowing the owner was fielding "security" to increase his concession profits before but not after the game.
