There's one black-and-white who stands out because he's taller than the rest. The Street protocol states that your avatar can't be any taller than you are. This is to prevent people from walking around a mile high. Besides, if this guy's using a pay terminal -- which he must be, to judge from the image quality -- it can't jazz up his avatar. It just shows him the way he is, except not as well. Talking to a black-and-white on the Street is like talking to a person who has his face stuck in a xerox machine, repeatedly pounding the copy button, while you stand by the output tray pulling the sheets out one at a time and looking at them.
