The D600 dust problem caused by delivery man!

I just received my D600 today, from Nikon Canada. The technician over there cleaned the sensor, and I must admit that, condidering how soiled the sensor was before (after some 4000 shots!), he did a pretty good job.

So, first thing I did: took a picture. You know what? There is still a dust spot. It must be the delivery man! It must!
