Prison Performance Anxiety

They're rebuilding the loos in a London prison due to some... er, directional problems:

Toilets in one London prison are getting a face-lift — or rather, a change in direction — to accommodate Muslim inmates who can't use them while facing Mecca, a British newspaper reported.

I've heard of guys who can't pee because other people are watching, but this is a level of performance anxiety with which I'm not familiar.
