They wouldn't let me carry nail clippers on a flight. I think the TSA thought I might attempt to trim my toenails during the flight.
LoL. I used to fly a lot a few years ago. I once flew to Pa from NC with a leatherman and noticed it when I got to my brothers house to unpack. I had a holy shit moment and couldn't believe it wasn't noticed. Was happy as hell I didn't lose it to TSA. RDU TO ELM thru DETROIT. MADE ME THINK WTF is their level of security.
I flew to Cozumel Mexico for a scuba diving trip this past summer. Without thinking, I threw my on my Reef flip flops...the ones with the metal bottle opener on the bottom.
Didn't realize those were the ones I had on until I hit the security gate and took them off. Got nervous as hell. I mean, if they're not going to allow things like nail clippers and a 5oz bottle of shampoo, why would they allow a metal bottle opener? My other shoes were all in my checked bag, so I had a feeling I'd be making this flight barefoot (if that's even allowed).
Luckily, they didn't seem to notice, or maybe didn't care. But still. TSA regulations are so inconsistent it's hard to tell what's allowed.
