Non b visa just for fun ?

[Baaksida]

I did get my Non B the usual way with a "Letter of Recommendation". The visa officer told me: "Do not apply next time without a work permit..."

My problem is, that I did not get the job after all, but need

a new Non B now, as I have a job offer again.

So, my question is, will I have problems this time, having "only" a "Letter of Recommendation" from the second firm, rather than a work permit, when applying for a new

(i.e. my second) Non B ?  

Or should I just go to another embassy/consulate, telling them, that my prospective employer did not give me the job after all ?
