The United Colours of Metro
Waiting for the 2.40 a couple of Fridays ago were : a regular who is a DVD pirate (he used to own a video library before net flicks put him out of business and this is his revenge) on his way with his bicycle to play Bingo, two hipster girls in black having a little snuggle together and one of the regular English as a Second Language class groups. One tall (and very talented) African guy is dancing with an Indian guy (bollywood meets zulu dancing) while the rest of the class clap and make whistling noises.
The Railways. Where different cultures meet. (Cut to shot of noble looking Metro staff (actors of course) staring heroically/stoically into the future)
