Do you know what I've noticed and find really sad? Over the last couple of weeks, and especially since Thursday, there's been a noticeable difference in a lot of my immigrant customers. They're making obvious deliberate efforts to make small talk / chat about sports and events / generally making clear efforts to, for want of a better term, "be liked".

Not that this is a bad thing in itself, of course the outcome of such efforts can only be a good thing. But the REASONS for it - the obvious desperation to be accepted and liked and not glared at or whispered about (and believe me there has been plenty of that) - is very sad.
