Well, if the TSA and airline want to keep me in my seat, arms folded, staring straight ahead for the last hour of flight that's fine. I can't stop biology. I hope you made those seats easy to clean, moron. Cuz I'll leave you a nice puddle. "Cleanup on isle 6!"
Oh, and maybe on the way out of the cabin I'll let the FA know that I have some disease which I don't wish to disclose but means that they should probably have a HAZMAT team take care of that....
