I had a similar thing with a promotional card at a bar called Wurstküche in LA some years back shortly after it first opened. The card said something like “one free sausage” on it. The intent was you use the card once, and then they take it away and next time you want a delicious gourmet sausage you need to pay. All of my friends had one of these cards, and eventually they all were taken away, but they never took my card and we kept going back to that bar over and over again to get sausages and drink beer.
