Do you get paid for working there? Well even if you do, that's still a nice way to experience and appreciate the real world, outside what many of us take for granted. I have a co-worker who is from Kenya, and he is the absolutely nicest person you could ever know. He goes out of his way to help everyone. He is also very intelligent, too. Has a degree in Computer Science and Nursing. Meeting people like the ones you did puts sterotyping /discrimination/prejudice, into perspective
edit: Happy after a long, hard weekend of night shift, off work until Friday!!!
