happy Oyster user on the day
To put a positive spin on this story, I travelled London quite happily on the buses for free all day Saturday :) my first journey was at about 08:15 and my last near enough Midnight. Okay, so it only saved me £3.60, but it's a feel good factor that counts here :)
I didn't have any of the problems suffered by many with extra fines or wiped cards as the bus drivers simply waved people onto the bus :) I actually didn't hear what the problem was until gone 6pm on Saturday.
