I don't have any tattoos personally but I've heard that sometimes the story behind a tattoo is better than the tattoo itself.
I feel like this is one of those cases as someone posted a video after a guy sitting next to them on a flight gave his buddy a tattoo while their plane was LANDING.
It's hard to see the tattoo itself, but it's on the back of the guy's left hand near his thumb. And he's resting his hand on a tray table, so a lot of people online were grossed out by it. Others just wondered how they got a tattoo gun on an aeroplane. Because that's gotta be illegal, right?
Turns out it's not. The TSA responded to a question about it, and said tattoo guns ARE allowed in carry-ons. So is tattoo ink as long as it's in a bottle that's 3.4 ounces or less. But we can't take on a nail file or clippers?
