I was out canvassing for the Conservative party again tonight. I came across another house with a 'Please take your shoes off' sign on their door. Disappointingly, the owner was not a Tory voter.
In my time canvassing in Stevenage, I have seen a total of three 'shoes-off' signs and one 'shoes-off' doormat.
Of course, the majority of people who answer the door are not wearing shoes inside.
