there are white people in croydon bars as well. bars in croydon arent the best place to find desirables anyway. there is no point hanging out where you think you might find a black girl hanging out. if you see someone you like the look of, whatever their skin colour, do whatever it is you do to chat people up. might be the street, a shop, a cafe, wherever. i dont really know what advice you are asking for? how to widen your hobbies so you meet more black people?
