I found the job centre to be quite comical. They clearly do not know their backside from their elbow. On the occasions I did go, I saw the same woman every other week and she was fantastic. She did genuinely want to help people get into work and was very clear to me about what the rules area so she gave me the information I needed to ensure I didn't get into any trouble.
I told her that unlike some people, I'm not in a rush to go and do 'any old job' but instead would prefer to hold out for the right one. She was very pragmatic and knew that forcing me to go into a job I hated would only lead to me being back in the job centre a few weeks or months later, so long term it wasn't the best decision. In the end we almost had a friendship
