If Ukrainian refugees enter Poland by foot, their first experience of the European Union is likely to be the Medyka border crossing. They then walk down a short path to get a bus either to the Humanitarian Centre, in an abandoned Tesco, or to Przemyśl railway station. A man who has driven a piano from Germany plays sad music. There is a candyfloss machine, and a Frenchman dressed as pirate handing out crêpes. Members of religious sects strum ukuleles, sing kumbaya, and pray loudly at people. Turn your back on the refugees and you could almost imagine you were at Glastonbury.
