We're in a family self-catering holiday in a long haul exotic location.
My father-in-law is from this place and has a terminal illness. This is his 'last visit' to his home country. He's paid for the flights and accommodation for the entire UK based family to go with him.
That's a total of 8 adults and 4 kids. My brother-in-law's parents have also come, bringing it to 10 adults and four kids.
The holiday revolves around my father-in-law visiting and spending time with all his relatives. There are gatherings and meetups planned pretty much every day.
For some reason, that the rest of us can't understand, my sister-in-law has invited a friend from the gym as well. Nobody else really knows or likes her. She appears to be ND, which may explain why she didn't politely decline the invitation.
She's staying with my brother-in-law's parents in a neighbouring villa. They'd already booked and paid for their accommodation, so they were kind enough to say that she could stay there for free.
This woman is now causing problems and arguments due to her CF'ery.
She's refusing to contribute to the communal shopping 'because she doesn't eat everything that's been bought'. We've always just split the bills by family unit. The kids obviously don't drink alcohol and are pretty low maintenance in terms of food. She's also demanding the kids are counted as 'full people' for any shared costs, etc.
Is it me or should she just fuck off? She's come away on a family holiday and now thinks she gets to call the shots on how we do things. The mind boggles.
Just to add, she's taken over the en suite bathroom in the next door villa that's she's staying in for free, despite there being another bathroom that was allocated for her use.
