There are times like what the OP says,
tho regarding taking the advice probably goes both ways.
I've seen people sound pushy as hell and like complete a-holes.
If they are neglecting to take advice properly, then you can say that there are always people that are neglecting to be courteous in giving said advice too, especially when they want the advice taken.
i try to be usually more subtle about advice, most pple tend to take it better when you offer them in ways that are more like:
"it might work better if...."
"when my friend runs this, they say its easier if you...."
