I was in a cafe in Brighton once, and who should stroll in? Ken Livingston! And this was when he was major of London! No security or entourage, just him on his own.
Now what he did next was a bit odd - he say right at the back of the cafe (understandable) and ordered and omelette or something similar - but I remember him cutting up all of the food on his plate into tiny little pieces before he ate it. It was really strange. It looked like food you would cut up for a small child.
Reminds me of when George from Seinfeld cut up his Mars Bar with a knife into little pieces before eating it!
