Because there's supposedly a make-shift one beside LT11. Thrilling as food for the next semester will have to be taken away in plastic containers and eaten in the lecture theatres.
It has its own fun, packing lunch to go and munching on something to keep from falling asleep.
Then again I hope it's not plastic containers but paper wrappers instead for the sake of environmental friendliness. Imagine all the waste generated by students daily!
A change would do you good.
