Finding a Bin in London Town: A Global Challenge
It a know fact there is only one bin in London Town and even the one has probably been removed in the last few moment, naturally, due to security reasons. I have just been chasing a kind man with the official bin liner across St Pancras to put the Lion chocolate bar remainders into its rightful place. I also had tea to take-away and was immediately sorry for taking it away as no-one would take the cup away from me afterwards.
… talk to the world with a concise anthropological theory explaining this (Darwinian!) phenomenon as soon as I get rid of this tea cup, legally.

Even if there’s no bin in London, the city remains clean, which is quite amazing! France is such a dirty place, even with bins everywhere
