Haha, I'm sure I did, hopefully not repeating myself on this thread.

You mentioned your stint at McDonalds, earlier in this thread. But that's okay.
I too had my shortest job duration at a McDonalds at 16. I put in my first shift of about 3 hours, realized it wasn't for me. Told them so, I was given the option of walking away no harm, no foul, and went and got another min. wage job at a Round Table Pizza. That job was on school nights, and I kept it until school let out for the summer.
Then I went back to being an apprentice mechanic every day, instead of just on Saturdays.
