The Filipino Reaction to Criticism

I've noticed that Filipinos, when faced with any form of criticism, whether it is something like a complaint to the manager of a restaurant about poor food or service, or something about their country, such as crime, corruption, crappy infrastructure, or whatever, will respond in one or more of three ways:

• Deny that there's a problem ("The food is excellent, sir, you're the only one to complain")
• Use the equivalence argument ("It happens in your country, too")
• Shift the blame ("It's all the fault of the US")

What they don't do is fix the problem. But then, why should they, if there is no problem and it's somebody else's fault?
