Excellent overheard phone chat from fellow passengers. No 1: Man in nasty suit talking loudly into Blackberry type apparatus: "mm, yes you might hear some noise, I'm in a car" (er . . . you mean bus) going over London Bridge. Yes I think we need to bring the product to their attention, the insurance industry has been waiting for something like this . . . blah blah, etc.
No 2: Well dressed woman with Prada bag size of Tasmania. "Yes, you could have said it was brunch with a Mexican twist."
In fact, bus was so slow, got off and walked.
