Task: Question Answering
Input (English): Context: All these folks come spilling out of the bar as our cab pulls up , poor battered bike on the ground , and we hop into the cab and drive away . Very memorable . THEN the cab takes us to some part of town we ' ve never seen and two 20 something year old guys run up to the car at a red light , bang on the glass , " can we split your cab ? " I mean sure . Hilarity ensued . I made them cover the cab . 
Question: Why might the men have been banging on random cabs ' windows ?
