Yes, but the person who ran out on the check in this situation is doing so in front of everyone on the planet. Good luck in getting service in another restaurant again.
Greece may well be able to pull itself out of its current financial crisis. But it's still going to hurt. A LOT. Since Greece put itself in this position, there was no solution that didn't include Greece getting Greek. By not staying with austerity, Greece is going to go through a whole lot of pain and is going to come out of this unable to borrow cash from anyone for a long, long, long time. Personally, I'd go for more pain and getting properly on my feet at the end of the day, but that's obviously not what much of Europe has chosen. Fine. That's their choice. The rational voter has always been a myth anyway.
That's the problem with running out on your bill from a restaurant like this. You're never able to get service at any other restaurant, so you'll go hungry at times in the future. The restaurant loses money. The restaurant's other ("good") customers end up having to pay with increased bills over time. In the end, NOBODY WINS. EVERYBODY PAYS. Greece WILL pay for the money they're defaulting on: they're just going to pay for it for a longer time and in more subtle ways than are immediately obvious.
Don't believe it? Try declaring bankruptcy and then trying to get a loan. Or even renting a house. Do you have any idea how much more of a security deposit I charge for someone with credit that bad before I'll rent to them? Does Greece really want to spend the next several decades being forced to put millions more up front in escrow (at worse if any interest) for international deals? Because that's what's going to happen. Which means Greek companies will have to charge more for goods and services than non-Greek companies, which means non-Greek companies will own an even larger share of the Greek economy than they already do. Which means more Greeks out of work, which means a larger Greek welfare state, which means a greater burden on the Greeks who do have work, etc., etc., etc.
That's the problem with the welfare state mentality. It isn't strictly economics (though how you pay for a state when half the population works for or receives welfare from the state is a difficult question). It's about the rot that happens when everybody defaults on their responsibilities and debts.
Which is fine. The Chinese will just end up owning more of Greece and France. Europe is doomed to be a continent of nothing but quaint tourist destinations anyway.
