Well, they actually managed to surprise me. While there was indeed a small amount of tat included, they were at least well-considered. As for the rest, I got a four-pack of beers (Fullers) and a stack of book tokens. Result!
All my calls are closed, my files deleted and the hard disk defragmented. The only thing left to do is to wander around the company, say my goodbyes and then off to the pub!
