Who is self employed?

I myself am not self-employed, but my best-friend's owns Hickory Body Shop right here in Longview (used to be Hickory when the shop opened in 1955) North Carolina. After working there for the summer, not only would I be hard pressed to go back there again for a job (he owes me an assload of backpay) but I don't believe I'd ever take my car there either...
