Dancing Queens

I call these gals, if you can refer to them as gals, as the Dancing Queens. They pull up yesterday in front of the shop, don't get out of their car, and proceed to dance and smoke inside the car outside the building. They stayed for about twenty minutes and then left. Never bought anything. Never even got out of the car. Well, actually, the one jump out of the front seat went into the backseat to "smoke a cigarette" (crack) and then they drove off.
