We used to clean at New Hall womens prison in West Yorkshire.
It was a pain in the arse.
If it wasnt bad enough waiting for someone to sign you in which could take ages you then had to be escorted by 2 guards everywhere you went.
There wasnt even the bonus of any decent eye candy as they were all tattood,roll up smoking d**es.
To summarize if you price well and are prepared to be messed about its worth it.
If like me you prefer a simple life then it isnt.
Cheers
