This is a “ticket-resto”, which I guess would be translated at a “restaurant voucher”. Some people get these from their work, if their employer doesn’t have a cafeteria. Since my university does, I don’t usually get these.
However, at one point in 2007, our cafeteria was under repair, or construction, or something like that, so we were offered these. I think I got five of ’em. I never used ’em, but it was nice to see one after all I had heard about them.
