Astrid Buffett, the wife of billionaire investor Warren Buffett, was overheard at Allen & Co's annual event in Sun Valley, Idaho, griping to resort employees about the price of coffee, the New York Post reports.
At the so-called “summer camp for billionaires,” 77-year-old Astrid Buffett was heard complaining about having to pay $4 for a cup of coffee, the Post said. Buffett's wife reportedly said she “could get a pound of coffee” for the same price elsewhere.
Warren Buffett, CEO of Berkshire Hathaway, is worth about $115 billion and is the seventh-richest person in the world on Bloomberg's Billionaires Index. But the Oracle of Omaha also has been known to be frugal. Bill Gates, a longtime friend of the 92-year-old, once recalled the billionaire pulling out a handful of coupons to pay for a McDonald's meal.
