I preferred 118118, because I rather liked their ads and their chief executive, when interviewed on TV, seemed a lot more straightforward and fair than his opposite number at 118888. However, I've found 118888 to be far more reliable when it comes to actually finding numbers.
[Chalky] Can't you find these numbers free-of-charge on the web? Sometimes typing the name of the venue (quoted) into Google comes up trumps. Then there's the BT, Yellow Pages and Thomson Local Directories too...
I've just watched a video of atoms bouncing up and down on videotape. I wanted to ask the Prof why he's stuck in the 1980's and doesn't use DVD instead :)
