I worked in Salford Manchester for three years as a supervisor on shift.
It was like the flippen UN, the Muslims would not speak to the Hindu's, the Poles would not talk to the Rumanians, the English would argue with Irish.
We had a guy from Nigeria who liked everyone 

At break time we all had a brew and biscuits, its funny at 3:30 in the morning on a night shift we all looked the same, Miserable 

The Eritrean  guy always tried to get me to come to his Mosque, he did not realize in Britain we are all pagans and watched football 

How do I get a green card?
