> Internet café to print off your boarding pass for the flight home?

You can print the boarding pass at the airline kiosk at the airport, at least in any US airport I've been to. I always do this.

As noted in a peer post I try very hard to do everything without a phone. I do have a phone but don't want to depend on it.

Boarding passes in particular seem very unreliable on a phone. I always have the paper boarding pass printed at the airport but for curiosity I check the phone app boarding pass. More than 50% of the time the phone app boarding pass hangs from bad connectivity while standing at the gate and I can't retrieve it. Fortunately I always have the printed boarding pass so that always works. Paper does not rely on internet connectivity so it will always be infinitely more reliable.
