I tend to be rather dull with my food (in other people's eyes). I like to think that I appreciate food they way it's been prepared. 99% of the time I don't even put salt on anything that's handed to me.

Ketchup on breakfast foods is very very common, although I also think it's very strange. I think it's also a love it/hate it type of thing.

I also think that mayonaise on french fries is odd.
