I should actually say I served one of the presidential candidates. It was about a year and a half ago. I was working a flight out of Florida. At the time it was rumored he might run for president.
The former governor who will remain nameless walked onboard and sat down in first-class. (I’ve had governors and former governors on previous flights, and believe it or not, several have sat in economy/coach.)
From the moment he sat down, he was absolutely absorbed in his smartphone. The only time he looked up was when I asked him which meal he would like for dinner.
He was focused on whatever he was reading on his phone for about three hours, made zero chit chat, drank lot of water, and then we landed.
He dropped out of the presidential race fairly early.
