Can anyone make a living as a professional complainer?

I don't know, but a pal tells me that a number of people travelled the world free by doing so. Their system was to complain bitterly about the attendants, "That stewardess touched my breasts/testicles, she's a whore!" and variations on that theme. Male attendants were also vulnerable, sometimes for sexual orientation reasons.

I'm using the past tense because the known offenders ane black-listed on all major airlines for international travel, because they can't hide their identities. I'll bet the sods are still around, though, and looking for ways to continue their activities.
