Not sure they are that friendly with no dirty history, i went to Hanoi Vietnam with 1 TV in my passport and NO other stamps at all. Stayed there a few days before apply, had all paper that was required and even more but still they refuse to look into my application. This rule that they had that you need to be out of Thailand for 1 month before apply a visa, i asked them for some official papers on this. They showed me a printed A4 paper with big letters : "Have to stay out of thailand 1 month before apply for a new visa".
So no dirty history and still not friendly, i would never recomend anyone to go to hanoi for a visa after my experience there.
They gave me my visa fee back that was a little friendly, but i wouldnt called them friendly anyway.
