It's a well-known fact that being in a position of power can sometimes go to a person's head, but in this case, it seems to have gone to the other end of Patrick Snowball's body.
Backchat heard that back in his tank commander days, the Norwich Union boss used to carry a wooden toilet seat around with him while on patrol. On feeling the call of nature, one lucky member of the tank crew would be told to find a toilet, clean it, and install Snowball's own toilet seat so that the boss could do his business in style.
