Best job- worked one winter as assistant manager of an outdoor ice rink in Louisville in the mid-70's. Every Friday and Saturday night it was a complete party with friendly girls, mind altering substances, and Led Zeppelin blasting from the PA. I was 23 and the boss. Lookout.
Worst- either selling women's shoes (my first job), or being a printer, which I did for 7 YEARS. Ouch.
