I sort of got fired from my very first job, 16, doing sales at Cricket Alley. (Women about my age may remember that store, and groan at the thought of it.) This place invented high-pressure sales...which I suck at. I went in to quit the same day they decided they didn't like me anymore, so I call it even.
Of the various jobs I've held...more than half the companies I worked for (and I'm including restaurants

...) either closed, changed ownership, or drastically reorganized within a year of me leaving. These weren't (I thought) fly-by-night organizations. It was freakish. For a while I thought I was a jinx.
