An airport encounter

So there I was yesterday night having three hours to kill at FRA (Frankfurt airport), working in a half-empty noodle bar -MoshMosh; if you ask (sort of Wagamama; with better beer but not as good dumplings).
Weissbier tasting meant I had zip to the gents 5mn only to find a middle-aged woman sat opposite me. The waitress (tasked with watching my possessions) later told me she tried to say someone was sitting there, to no avail. Those long tables were quite narrow, so I felt a bit annoyed for a short while and then resumed crafting a powerpoint on my laptop.
She orders food, I eat a pho and then the next thing is that she spills her white wine on my laptop. She mubles sorry, I say nothing but am profoundly annoyed. She wipes it -ineffectively-, I mention she could drink champagne as it doesn't stain since it also made it onto my trousers. She answers it should not stain, to which I say I'll have to take a trip to the dry cleaner. She looks ashamed, glances sideways without a word for a good 10 mn, then picks up her things and flees without uttering anything else.
I was amazed by so much rudeness and wondered whether she would she have offered to picki up the drycleaner bill if she was a bloke? Anyway, I guess I'll go to a different restaurant next time, maybe Hooters?
