Some years back I was unemployed and in the unemployment office. I found a job posting there that seemed to be a perfect fit, yet when I spoke to the job counsellor about it she discovered the position was filled and refused to give me any contact information for the employer.
I got a bit angry at this, so I snatched up her file on the employer and walked out of the office with it. I went straight to see the employer, told him what my skills were, and explained that he needed me whether he realized it or not. I guess he was a bit surprised at my approach, but told me I could start the following Monday.
