Wow, look at all the extra storage you would have in one of those. You could probably lighten your luggage a bit by keeping the stuff you want to access quickly in the pockets of that kilt. That guy had the right idea, think of all the beer cans you could stash. Of course, I suspect going through the terminal inspection process might be a bit frantic.
@antedeluvian interesting, yes, some men do use handshakes as regular greeting, and in some more casual contexts that turns into slaps on the back, etc. As for the son shaking his mother's hand, that's an interesting one. We'd have to do some research to ascertain if that is indeed a Swiss custom or unique to this particular family.
