pg: Let me walk you downstairs and help you hail a cab.
vendor: It's ok. I've got it.
pg: Ok but remember, if you get a gypsy cab, be sure to ask the rate first and negotiate. If you take the yellow cab, it's a flat fee.
vendor: How do you know it's a gypsy cab?
pg: Uh. silence You just sort of know.
vendor: I'll stick with the yellow cabs.
pg: Good call.
