Big Mac tries to be everyone's friend and loves nothing more than sharing a few jokes over a hot cup of tea. When things don't go his way he can be overly sensitive, and just a little bit grouchy. He's unlucky in love, but ever the optimist that this will change. He loves his country and he's very proud of his service in the army.
His role within the team means that he gets a unique insight into the patient's lives as he ferries them around the department. He's a big gossip, and the whole ED team love him for it.
