Earlier quoted context omitted.
You find it normal to carry around passports for domestic travel? How often do you travel?
I travel with work a lot. Seems normal to carry some ID like a passport when travelling, to me. Hotels often ask for ID. You don’t know if your plans will change and you’ll need to fly straight to another country, etc.
It's certainly not happened to me, and I'm in the quite unusual position of being someone who's traveled internationally for business on In other words, no, I never take my passport with me unless I leave my house intending to leave the country.
