"If you're gonna spew, spew into this."
When I was working with The Calgary Eyeopener in December (CBC's local radio morning show here), I did a little cab-hopping to talk to drivers about proposed bylaw changes. Basically, taxi drivers here want to be able to charge passengers a deposit if it looks like they may toss their cookies in the car.
[N.B. This isn't the first time I've asked complete strangers about bodily fluids. A couple years ago for our local afternoon radio show at CBC Halifax, I asked, "have you ever peed in public" -- but that's a different story].
