Why do recruitment clients ask for poor service?

I have worked as a professional recruiter for almost 12 years and it still amazes me that some clients insist on receiving poor service from recruiters – in fact they request it!
Picture this…

A client (let’s call him John from ABC Limited) needs a new manager to join his team. This need is pretty urgent as it is due to the previous incumbent resigning and now working his month’s notice. So what does John do? Now, if he is new to recruitment he may Google agencies within his sector. If not, then he may look up his recruiter contacts he has dealt with over the years. Either way, he will have an overwhelming urge to contact lots of recruiters and brief them on his requirement.
