Might just be me, but I'm detecting a hint of bias for your sister from your parents. When you get shortchanged and don't even make a third of what you should've, they're hitting you with the 'what does it matter, its work experience!' line, while when your sister gets similarly shortchanged whilst working just a few days more, now all of a sudden it became a scam. :mjlol On more of the topic of the camp though, fuck them for doing that. That's taking being shitty cheapskates to a whole new level.
