If someone threw a bottle of hot sauce at me during a high pressure situation, I wouldn't care at all about what they have to say to me. If she had approached him respectfully, without an unprovoked physical attack, he would have responded much differently.
See the comment above from someone who was sitting near her; she was trying to toss it back up to the stage to return it to him (and tried to get his attention so he could catch it) but it didn't work out. She also gave every indication of being mortified when the bottle burst and splattered people.
She certainly wasn't trying to bean Noah in the head with it, and I don't get the impression he would have thought that either.
