I believe Wal-Mart practices their preaching even at the higher levels. For example, I know a number of management consultants who work for the big brand name consultancies. They travel each week to work at their client's site, and usually stay at classy hotels: the Ritz, Four Seasons, etc., and the clients don't care because they already spend $X million on consultants, so who cares if they're spending $500 a night per person for hotel costs? Besides, they're advising the board, or the president and C-suite, so there's no point in worrying about costs. But Wal-Mart cared. The consultants had to stay at cheap hotels. (For these people, that was traumatizing.) Their receipts were reviewed and per diem spending caps enforced. (Very uncommon. These people like to rack up $1,000 bar tabs and charge it to the client.) Most of the team did not even fly down there, to save costs. (Seems obvious, but that's not usually done.) That made them an unpopular client among the jet set, but they sure saved a lot of money.
