Ride through

This is a story I heard from a friend of mine:

Her brother and her bro's pals finished up their XII standard exams in Delhi. They wanted to go out and have a good time. They decided to go to McDonald's and have a fancy meal, but they were also in a rush to catch a movie. So, they decided to try the drive through. When they got to the window to order, they were refused service. Why? Ummm, 'cos bro and pals had decided to ride through the drive through in a rented rickshaw (no no, not the internal combustion engine driven, but the pedal wala). Hehehehe!
