Today I was talking to a citizen of an Eastern European non-EU country. Previously this person had been spending time in Germany and had obtained a visa from a UK consulate over there to do research in Edinburgh. Because the sponsoring organisation screwed things up, my contact has to fly to Germany next week for a day merely to renew the visa. It can't be done here. The only way to get back in time for appointments relating to the research is to return via London. So, three completely unnecessary flights are to be undertaken simply because the authorities are living in the eighteenth century.
