Do you ever go off the set and scare people outside?

I did want to go. There�s a Starbucks not too far away from where Buffy shoots. Unfortunately I never got the break, but I wanted to one day hop in the car and drive there and go and order. "Yeah I�d like a latte please. What�s the matter? Do I have something on my face, what�s the matter, is there something there?" But I never did it.
