Well, now, don't I feel like a cheap w****? While I don't think $150 would be worth feeling like cr@p for the next 24 hours, I think $500 would get my attention. But only if I get to pick the day and clear my schedule first.
Of course, I wouldn't like that to be my steady income or anything .
You're very fortunate if your reactions only last for 24 hours. Mine last a week at minimum, up to two weeks. And the last time I had a large amount of gluten on accident I ended up getting brochitus which turned into pnuemonia, requiring several pricey breathing treatments at Urgent Care, chest x-rays, consult with a pulmonologist, etc. I was sick for 3 months because of a restaruant mistake. Even if I were in need of the money and decided to do this I would require that they also sign a contract that they are responsible for paying any medical bills incurred. But even then I just can't see giving up my dignity (in allowing them to film my suffering) for some money.
