Working as a contractor you come into contact with a wide range of company 'cultures'. The longer you're there the more likely you are to experience the weird edges that don't marry up with the rebranding exercises.
I've been working at an agency for a couple of months now and I'm coming towards the end of the contract. One of the big things that changed about a month ago was I got a Mac to develop on. What I didn't realise was I also got a new first line technical support dude. Let's call him Algernon, or Algy for short (the names have been changed to protect the guilty).
