Amber's not leaving yet

As you weave among the trees walking back to your van, you think you hear Karen's soft voice. It is followed by Amber's bitchy bark. Listening to their voices you are soon in their sight. When you get near the girls you see the problem. There is a car touching Amber's back bumper. There is a jacked up pickup blocking her in front and even then it doesn't look like she can get her car out. Karen sees you and sensing you don't like Amber (and unknown to you, she has a crush on you) turns on her charm.

"Kevin?" she asks sweetly, "Could you help us find the driver's of these cars so my cousin can get her car out and get us home?"

You know that finding the owners is near impossible and that they are probably too drunk to operate their vehicles. It will be dawn before all the cars are removed. You are still sober enough to drive your van back to town. The trip would be over an hour there and back and gas burned. You wouldn't get the girl unless...

Do you tell them you can help or say nothing can be done?
