That's really odd, potatoes aren't part of any English breakfast I know. A full English would be bacon, sausage, eggs, fried tomato, mushrooms, black pudding and maybe baked beans and fried bread. You do see hash browns sometimes but that's an Americanism.
Those must be some cheap ass campuses that I had to eat in then. Every body from all around the world was living on one of the two snack machines.
And the chocolate they offered were terrible, but we had to eat it.
