I remember a gamedev complaining about this on Twitter but the outcome he came to was that he hated that Linux users submitted bug reports, stating the OS itself was broken and he refused to help any of them.
One thing that came as a culture shock for me is that I'm used to driving like 4 hours to see relatives. And this is usually several times a year. Then I heard from some Britons that they have rarely visit their relatives who are only like a hour drive away. Really messed me up the first time.
