Fred is very, very, surprised and asks for clarification.
HR: 'Which part of it would like clarification on, Fred?'
"The bit that says 'Fred no longer works here.' I was under the impression I still did."
HR: (short silence).... 'but you handed in your notice, Fred, to go self-employed?...'
"Yes but, no but, yes but, I thought I could still do both"
HR: silent mouthing of WTF!
