Black Friday - Friday the 13th

During lunch on the street, a row of gentlemen in black were marching in a straight neat row, a can of coke Zero in one hand, a black umbrella held opened on the other, a solemn and almost mourning expression on their faces. Cool advertising eh and pretty smart too, Coke actually used today - Black Friday to promote their Coke Zero.... really attention-grabbing and hard to not notice.

Now that's marketing. So what if its black luck...Hah!
