When people go to Times Square for New Years Eve what do they do if they have to pee?

It does not look like there are any porta potties and I am sure none of the businesses would let you use the bathroom. I am sure a lot of people have had many beers and outside of just peeing in the street I do not know what they do.

DOH
D'OH
