2 . Get your compensation later, even if that means vouchers
Yes we know we said no to vouchers but in case companies have a hard time handing over a check right there and then, do not just walk away with a promise to get one later. Write in your complaint that you are ready to accept vouchers for future services or frequent-flyer miles and they are more ready to oblige. In this way you can walk out with something which promises you of future compensation.
