I didn't know real people really did this--I thought it was only on the Muppets, or maybe shows set in New York.
But yesterday someone walked up to me and, speaking in a low voice, offered some sunglasses, Gucci lookalikes, cheap. Or, if I didn't want those, he had any number of knockoffs, all at bargain prices.
Unfortunately, he wasn't wearing a trench coat.
I suppose that is too much to expect in Southern California.
