On the left, fast food, and on the right slower food:
The Speed Burger bikes on the left were photoed by me in Quimper, Brittany, in April 2018. The taxi advertising Just Eat food was photoed by me earlier this evening, as I walked home from a meeting.
I photoed this taxi with the permission of its driver and (presumably) owner. I told him I liked to photo taxis with interesting adverts, like his taxi, because such adverts are a relatively new thing in London, and because particular adverts will soon be gone. He told me that his advert was especially interesting because it had to be changed. The original Just Eat advert had been for fast food. But then the Mayor of London banned fast food adverts wherever Transport for London is in charge, which includes on taxis, and a different advert was stuck on the taxi, advertising Just Eat food that is slower.
