I’ve been boycotting Starbucks since the early Noughties because of their aggressive business tactics; now I’m joined in that boycott by hordes of people who are unhappy because of the company’s attitude to tax. Now I know how Michaela Strachan felt when statement earrings came back into fashion: pleased, slightly righteous, and tempted to shout “I was doing it first!” a lot.
