Surely they were lying. I once saw a redditor post that they broke their leg, went to a hospital, got taken in immediately, got all fixed up, and left without paying a dime.

And because that one unverifiable post must be true, and because it only affected one person, then the entire NHS must be functioning properly and anyone who says otherwise is a liar and a literal hitler who thinks health care isn't a human right.

(/sarc, but I believe there are people out there who genuinely think like this.)
