Thanks everyone for the replies.
I have finally done my renewal and it was a bit of a non-event (not that I am complaining). The queing outside didn't last particularly long and once inside I was called withing five minutes to hand in my paperwork and after another 15 minutes or so I was called for the interview.
The interview was all about nothing. Everything was in conversational tone, none of the posturizing that Americans specialize in and which so get's on my nerves. Just like Munkeh posted, only two questions: How long have I worked for my current employer and who did I work for before that? Again, both were on my form.
I do suspect though, that had I been born in, oh say, Bagdad, the interview might have been of longer nature. I wouldn't dare suggest profiling comes into it though.
