"A flight attendant should stop this s*** before anyone has a chance to point this out," another wrote.
However, some gave her some sarcastic pointers just jabbing his foot with a needle, or even licking.
"I'd start just lightly scraping my fingers along the bottom of their feet. Make it as uncomfortable as possible ... they'd never do it again to anyone on a plane," one person said.
Another wrote: "Don't think I'd be scratching it directly under my head ... But maybe also licking my hand and rubbing it on their foot."
Someone had also shared their own story writing: "I was on a six-hour, overnight flight a couple months ago, someone up ahead was doing that. It was shut down by a flight attendant pretty quickly."
