I am an American citizen so you can take it from an American citizen instead. Companies have zero scruples whatsoever about screwing over others in business.
Then it isn't "standard American bullshit". It's just "standard bullshit".
After seeing it first-hand, I'm noticing this attitude even in fields like global politics, where burning goodwill to gain very minor advantages seems to be the policy these days.
But that's the thing... do you have access to a representative, uniform, random sample of US customers? Do you have a similar sample of customers from other regions to compare against? Are those samples based on your actual data rather than personal anecdotes? Have you eliminated hidden variables that could better explain this behavior than simply the place they are from?
If you answered "no" to any of the above, you're suffering from availability bias.

And that one is called confirmation bias.
That's a really prejudiced and unwarranted view of Americans. If anything it says more about your biases and prejudices than it does about one nation.
