I tend to bring 3 bags - laptop bag, gym bag for after work (on-site) and handbag. It's a bit annoying actually but I can't really do without any of them, unless I skip the gym.The amount of luggage people bring with them for a day at the office. Those folks you see every day on the train/tram/bus with their 3 bags.
Doesn't directly please me, more it bemuses me. And I find being bemused pleasing.
