I had a guy knock on my door a couple of weeks ago, canvassing for his window cleaning services.
My sign written van was literally 3 yards away from him, he asked if i was interested in a window cleaning service,
I just looked over his head towards my van and a couple of times nodded my head towards it.
He seemed to get a bit agitated and said " what "
" what " then turned around and said " oh, is that you "
I just smiled and said " yes mate " as he made a hasty retreat
