Thanks guys.
It's not for my current job, in fact I e just gotten a promotion to team leader.
I know someone who is managing another place where the job is. When it was first mentioned it was more money and the manager knew how keen I was and agreed that id be good. It was more responsibility.
The manager then offered the position to someone else I know without talking to me again.

After sleeping on it over night I'm not so annoyed. My current job will eventually earn me more money and perks than what the other place is now offering. So staying where I am
