When the TSA announced they would stop asking those asinine questions at airport check-in, I had a follow-up suggestion to the TSA which has oddly enough not been implemented:
People sitting next to me tend to be a bit odd. Whether they’re a threat to the plane, they’re certainly a threat to me getting anything productive done on the plane. So if it’s threats they’re looking for, maybe that’s a place to start.
Note to TSA: this one’s on me.
