When chatting to a gate agent waiting for a flight in disc econ this week, she gave me a pile of vouchures (unfortunately not upgrade

). But I have no idea if these are for use on the ground or in the air.
Hence I was wondering if anyone had received one before - no speculation, I can do that all by myself
They are light grey and about 7cm by 15cm in size. With no writing or terms and conditions on the back.
Text is 'We hereby invite you to the refreshment/meal as indicated below. Please hand this card to the waiter when ordering'
Choices

Flight No/Date:
Ref: SAS 1317.001
The GA said they were for use on the plane, but looking at it, it looks like what I would expect when delayed. If used on the plane, for instance if they were what SAS gave out when making the changeover that is fine and good, but f for use on thr ground at a non SAS business and AS refused to cough up the money I would be a little guilty.
