Language blogger S.A.P. over at The Economist confesses his morning ritual:
S.A.P. doesn't order a nonfat latte (easy on the foam) every morning. "Sam" usually does, though. I have a relatively popular male name: not ubiquitous, but familiar enough—in India. Stateside, Sam sounds vaguely related, so I've taken it on as my Starbucks name. Sam orders my coffees and makes restaurant reservations for me. He introduces me in short-lived conversations. His name is quick and perfectly dull, and unfailingly spelled correctly by the barista on my cup. I envy Sam sometimes.
