In the custody suite
I really am not a fan of Eastenders. I don't even own a television and had to ask Richyrich how much a tv licence costs.
The above picture shows the characters Ronnie and Roxy Mitchell who were arrested and loacked in a cell together in an episode of the soap a while back. As is normally the case in our police stations, their shoes are removed. One of them (I watched the clip on You Tube) threatened to sue if her shoes were damaged. Maybe she had seen that episode of Sex and the City where Carrie has to remove her shoes (Again, I watched that on You Tube not on television).
If one must remove shoes to protect a police cell from damage and dirt, how much more should you remove your shoes before entering your home?
