When you go to a concert you know that you're going to have to pay a lot more than you normally would for a glass of wine, beer, a cocktail, etc.. You may be, or have a friend who is "crafty" and can find a loophole in any rule.
Like this woman...who hollowed out a baguette so she could sneak wine into this lovely event. Was it necessary? No. But was it crafty? Yes!
