Depends what kind of programmer you are. A professional is going to try
and run the procedures as near as possible to the way the employer
wants, but if someone is going to hire you, then tell you how to do your
job in a way that you feel is wrong, you are going to say, "sorry, you
need to get someone else". If you hire a plumber and tell him where
you want the new sink, he's going to do it. If you stand over him
and tell him you want teflon tape instead of joint compound, he's going
to tell you "you wanna do this Mac" ? If you tell an architect that
he has enough support in that building to meet code, and you want some
of the beams taken out, chances are good that he's going to roll up
his drawings and walk out.

I've been in this business 30 years. You are going to get a few stories
in 30 years.

No. I made a conscious decision that it wasn't going to work out with this
guy. If you fault me for anything, fault me for not being brave enough
to just say, "this isn't going to work out, thank you for your time",
and leaving. I'm not sure that would have left him any less angry.
