This is getting ridiculous – this afternoon I was asked to give written permission after I was filmed eating.

I was in central London and had sat down to review the images I’d just taken of a performance by these Japanese musicians, Okinawa Eisa. Two English women in kimonos were offering noodles – they were promoting a stall nearby – and they had just reached me when a 6 strong film crew appeared and I was on one a number of people filmed.

The crew quickly moved on, but one stayed behind and explained they were from BBC2 and asked if I would sign their consent form. Apparently they now do this whenever they film anyone, just in case. Ludicrous! It was hardly as though they had filmed me covertly and I’m sure the footage shows I could have got up and moved away had I not wanted to be filmed.

Maybe the next time a security guard hassles me, I’ll ask them if they have my consent for recording me on their CCTV?
