Well, this is a bit off topic but one of the things that come to my mind is, for most forms of prayer atleast: Isn't it pretty much like telling God what to do? Even though it's a request, you gotta wonder when it's so specific if they even consider the possibility that their perception might not be all it's cracked up to be. Of course, you can always use "not my will but yours" disclaimer, but lots of people seem to know what they want God to do for them. If a prayer is full of statements without many questions, that would be very telling.
But to get back on topic, I'm sure most of us have had that experience where someone says they'll be praying because it was their judgement that you are lost, and basically they are telling God "hey, do something about this schmuck, he's wicked and worldly and stuff" (but in a nice way with nice words, because it's God after all - assuming they actually pray) Of course, the irony here is that they are the most lost or at best equally lost as the ones they are speaking to - so my feeling tends to be one of sadness at the ignorance.
As a few have already stated in the thread, it does ultimately depend on the person's intent, of course. For example you might have a little girl who excitedly tells you that she'll pray for you simply because she likes you and actually think you're a good person, and she wants you to be blessed, prayer is simply the most logical thing to in her world view. This can even happen in the same situation with an adult that is judgemental of you, but you'd be able to see the difference. In a situation like this I wouldn't be too concerned about what the little girl has been taught, because obviously the important thing for her is the love, not any kind of judgemental attitude. Even if you've got a more sophisticated world view, it doesn't mean you're less likely to be judgemental. The same goes for this caring attitude too - there are very intelligent people who has this kind of outlook on life. A person's attitude doesn't necessarily have to do with their intelligence, perhaps it just amplifies what was already there.
