well personal i really wouldn't care i would still talk to you we may even become friends or lovers (you never know) if you are really worried i think some uni's offer muslim halls or something if you do decide to go out (no you don't have to drink if you go out) i would recommend losing the hijab just for the night as it means that you will blend in a little more of couse thats just a suggestion it's up to you good luck in uni
