Point taken - but trust me, ours really are *that bad*. Think of it like fast food... many Americans think of McDonald's food as fairly crap, right? Not too nutritious, a bit cheap and nasty? No substitute for your local diner or homecooked food? Well, imagine tiny, *tiny* burgers that taste of even less, cost twice as much, and are served at a snail's pace by bored, spotty youths whose "have a nice day" is rendered with such dripping resentment and hatred, you'll wish you'd starved instead.
That's the sort of thing I mean when I say our psychics are weak versions of the American ones - you'd rather not bother with any of them, but the "originals" are at least value for money and made of 100% beef. Wait, I think I'm losing my analogy...
