It's funny that your first impression of the guy said A-hole. My experience is similar but on the other end of the spectrum.
In my experience, most of the people I have met who seem to be friendly and helpful at first turn out to be the biggest pricks/b*tches of all.
I have come to judge excessive niceness from strangers as a warning sign of trouble.
By the same token, people who initially seem distant or uninterested usually end up being down to earth and easy to get along with. Go figure.
Can you ask your boss to give me a raise too?
