Oh yes...I remember something like this from forty or so years ago. My father worked for an American company that required of him a great deal of international travel. Airlines issued vouchers back then to FFs? A corporate cost-cutting measure began, requiring that those vouchers revert back to the company. I recall my father complaining that the division accountant refused to accept any expense reports that did not have the airline voucher stapled to the front.
Nothing new under the sun!
