I've noticed in the several years of reading these boards and talking with people offline that people here in the US really do seem to have an expectation that if anything at all goes wrong with a restaurant meal, they'll have part or all of their meal comped.
Posters to this board, in particular, often gripe when they receive an apology rather than free food, which I find kind of stunning, especially after several years of living abroad, where no such expectation exists at all.
I'm interested in hearing how people feel about this sense of diner entitlement to free food: where it comes from, what consequences it has, and whether it's a good thing.
Personally, I'm torn. I like that we have high expectations for service and quality, but I worry that we've created a greedy monster in the process.
