I personally wouldn't feel the need to tell someone that they made a mess, but to say that she doesn't have the right to say anything sets an unfair precedent.
Perhaps she was put off by the fact that she could have slipped on something, or just found it annoying that something spilled, because she likes everything around her to be clean. That said, I don't know if "making a mess" in working produce is unavoidable.
I tend to empathise with people there... unless I'm in that situation myself 😂.
Seriously, though, try not to let other people's behaviour get to you, no matter how annoying you think it is... because there's much worse out there 😅.
