Becky - Where Can I Go This Time

Becky is an air stewardess who wakes up in the back of her car, not at all sure how she got there. When she tries the doors she finds they are all locked, and that the electronics have been fried so that the locks won't open. Worse still, she's been asleep for hours and is dying to pee. She searches around desperately for something to pee into, rather than ruin the interior of her car. She is frantic by the time she finds an empty coffee cup under the driver's seat. She pees into this and fills it, but still needs to go. She finds a clear plastic bag and continues peeing into that, but then she has to stop because it is leaking. She pushes the bag inside a shoe to stop her pee going all over the floor of her car. Her dilemma is far from over, however, because she stills needs to pee and there is nothing left to pee into. What is she going to do?
