This lady tried to rob some teenagers in a QuikTrip bathroom…

Maybe it's time for a ranking of the 10 Worst QuikTrips in the Tulsa area.

Over the weekend, the "Face of Meth" poster child pictured above – Christine Cook – pulled a knife on a couple of teenagers in a QuikTrip bathroom in a daring attempt to steal a pair sandals.

Like most idiotic, under-the-influence of meth or bath salt criminals, she was unsuccessful.

Via The Tulsa World:

A woman who reportedly robbed a teenage girl inside a convenience store bathroom while armed with a knife was arrested Sunday morning, according to police.

Officers responded to a call about a woman who refused to come out of a bathroom at a QuikTrip in the 4900 block of South Harvard Avenue about 9:40 a.m.

The woman, Christine Cook, had been inside the bathroom when two 15-year-old girls entered. Carrying a large kitchen knife, Cook allegedly locked the bathroom door and robbed one of the girls of her sandals, police said.

The girls managed to escape, and Cook, 40, attempted to flush the knife down a toilet, according to police.

Police managed to take Cook into custody without incident, but she later attempted — unsuccessfully — to escape her handcuffs. She told police she had intended to assault an officer with his flashlight and steal his police car.

Okay, you just attempted to flush a knife down the drain and unsuccessfully robbed teenage girls, but you really thought you were going to beat up a cop and steal his car? Say what you want about drugs, but at least they give you confidence.
