“Keep Britain Tidy.” The clear message in bold lettering, complete with the logo of a little figure hovering next to a bin, was unmissable. Especially as it was emblazoned across the base of a takeaway pizza box lying in the middle of the footpath . . ! The command was somewhat compromised by the context but, nevertheless, I obeyed and took it upon myself to keep Britain a little tidier by picking up the box and adding it to our recycling pile at home.
