Why do people like those idiots go to university anyway?! Its a very serious issue that you basically arent eating because of some bums. Definitely speak to a manager, it'll be in confidence and the problem will be sorted. I can understand how you feel, it must be terrible being put off eating properly and buying takeaways - you just cant afford to do that at uni. The problem wont go away, the sooner you get it sorted the sooner you can start eating properly and the more money you will save. Im sure they will let you transfer rooms if possible. Dont suffer, you have EVERY right to be there too! I hope everything goes well for you.
