The Belgians I've known simply want a straight answer.

Americans will make up a hundred reasons to not do something when they don't have a technical leg to stand on. I was starting to hate this Belgian guy because he wanted something done and I didn't want to spend the time required to do it. Finally, after coming up with all sorts of excuses, I just told him the truth and thought he'd storm out.

He just said "Fine! Now we can go have a beer"

Belgians are definitely also full of shit, but in our own special way. :-) I guess it’s more of a cultural thing, where you expect something and reality is something else.
