Out of curiosity, are a certain nationality or nationalities more prone to this attitude in MESCO's experience?
There was a phase when it seemed to be almost exclusively an American thing, but I think that was just a statistical blip. Most recently, in no particular order, a British-born Australian, a German, an American, an Australian and a Dutch couple. To be honest, the bulk of divers who come here are Australian, with a smattering of New Zealanders, intrepid Europeans and a small number of American, mostly yachties - we're a long way from anywhere and hard to get to - so I'm not sure you could derive anything significant about national psyches or the state of dive education in a given country.
Thinking about it as I write, probably the largest group of arguers would be defined by the fact that they are on yachts rather than by their nationality - I'd guess that they form a group who are more likely to end up in a remote dive location without necessarily being there specifically because they want to dive and can end up going to a lot of great dive destinations without racking up a lot of experience, whereas people who travel here just to dive tend to be more experienced divers anyway. Or something.
