Beckham thought it was a put-on. “Is this guy taking the piss?” he asked. But the waiter was serious. When the Galaxy’s Portuguese defender Abel Xavier couldn’t produce an I.D., his wineglass disappeared too. “What is this?” the 34-year-old Xavier thundered. “I have a kid who can drink.” The other players laughed hysterically, partly because the waiter hadn’t recognized the world’s most famous athlete and partly because Beckham and Xavier were so used to being mobbed in Europe that they didn’t bother carrying identification. Welcome to soccer in the U.S., guys.
