mate stuck it out, i mean you are only there for a short time till you get back to uni, is not as if is a life long career. i am in a similar situation, i work night shifts at a sainsburys supermarket and most of my colleagues are from bangladesh, most hardly speak english, they don't invovle me in their convo's, the only time they will talk to me is just probably to ask me to do something, but i don't really care cause i'm there to work not to socialise, i need the money as i am also starting uni in september. my advice is do not quit for any reason, go in and do your work and get out once your done. i am sure you are allowed to listen to your own music on an mp3 or something so get one in every night and entertain your ears with some good tunes, before you know it the nigth will be over. have to say i do a 12hrs shif like urself..
