This is why they have toothbrush holders in airplane bathrooms
Flight schedules don’t leave much for personal hygiene rituals. That’s why airplane bathrooms have toothbrush and shaver holders (take that, Jerry Seinfeld!). The sad thing is that nobody uses them! Take this guy, who was in such a rush in the early morning that he didn’t finish brushing his teeth in the airport bathroom.
We get that you don’t want to offend other passengers with your stanky breath, but nobody wants to see toothpaste foam coming out of your mouth! The OP was a dentist who appreciated this guy’s dedication to dental hygiene, but as a seatmate, he wasn’t so happy.
