Cashier: "Are you staying for the zombie walk?"
Me: "There's a zombie walk?"
Cashier: *gestures at parking lot* "That's what the tent and the music are for; there's a zombie walk to benefit Gleaner's Food Bank."
RX: "There's a gun show in town this weekend. I'm not sure it's such a good idea to have a gun show and a zombie walk on the same day."
