‘Be well’. This is what you hear now at the checkout counter at Walgreens, the largest drugstore chain in America. Employees offer this valediction as they hand over the receipt, and it comes across as eerily sincere. In fact, the phrase was so effective at rattling me out of my consumerist stupor that I said it back – ‘Be well as well’ – but it didn’t quite come out the same way. It sounded mangled, faux-British, and for some strange reason I raised my voice at the end, turning it into a question. I left feeling confused.
