I am glad to see this has improved your travel preparation- I have learned the hard way too! I see your point but my perspective is that this approach protects me in a potentially adversarial situation in a location where I am at a distinct disadvantage: I most likely don’t speak the language, aren’t familiar with cultural norms, and unfamiliar with the surroundings. With paper, I can point to my reservation number or booking details unambiguously and prove my point. If they need to take the paper to someone else to verify, I’m not giving up my personal cell phone and only method of communication at the same time. It’s like when you learn to drive: you are taught, you could be right in a traffic situation but at the end of the day, you adapt to the situation. Better to have bent to someone else who did something wrong but stay alive rather than dying “proving” your correctness.
