V is for Vernacular

A little while back I had to put my car in for a service and took a half day off work to go and pick it up in the afternoon. I rock up at the garage and I see that the mechanic is still working on my car and am told that I have to pick it up the morning after. No problem I say and call a cab to take me home as it's pouring with rain. Cab arrives and it's a big MPV thing, a Citroen Picasso or something. The cab driver is a genial fellow and wants to chat.
