Well, we all are a bit xenophobic in our perception of the world around us, there is always a notion of "us" and "them" hardcoded into our brains. And when one of "us" is bad we think "this dude sucks" because we think of him/her as a person. When dealing with a foreigner, and specially in an online, very non-personal way through a middle-man, for us that person is always just one of "them". If he does a bad job we will almost always jump to generalize the situation and get a "these guys are stupid" conclusion (works the same way with the positive experiences too). You never do that with "us", because you know it's not true, you know there is a lot of brilliant people around you, but you don't know "them" good enough to be able to think outside the black & white picture of your very limited experience.
