Spotted...

^^^I saw you riding past me on Aldwych this morning, I'd already got to work, changed into my secret agent outfit and was walking to a secret assignment in Pimlico, so I was unable to shout anything, as it would have blown my cover.

I was super late because I botched a puncture repair. You need to change your secret agent persona into one that yells random things at traffic. Then you could get away with it.
