Is that clear? OK, I'll proceed.

So we arrive at the next station: "This is.. Waterloo. Change here for the..." Now, the signs on the wall clearly say Oxford Circus. The mosaic on the wall is clearly the one at Oxford Circus. But Automated Posh Bird isn't so sure: "This is Waterloo. This is Piccadilly Circus. This is Oxford Circus." The two Spanish lads opposite me grab their bags and flee.
