The key is preparation. It’s the same for me at hotel check-ins. I’m always prepared, I have all my info available in my mobile or on paper, I’ve already thought about the trip several times before and on the way.
Some people seem utterly unprepared. They either don’t have their info at all, or have to login to their web mail, or find some printed paper at the bottom of their enormous suitcase. And then they tend to have tons of questions. I check out the facilities beforehand online so I know what to expect and how to use them.
