Spilling coffee that is not at such a dangerous temperature is, as Fyron pointed out, no big deal. You stain your pants, you yell, you go on with life. So while you know that you just might spill it, you have a reasonable expectation that if you do you won't be badly burned.

It's not about whether she thought she was going to spill it, or if the thought even occured to her that she *might* spill it. It is not reasonable to expect that spilling coffee on yourself would cause burns severe enough to warrant hospitalization.
