Well, it seems to me that there has been absolutely nothing said or implied that leads to the conclusion that successful applicants will be able to eat cake. Quite the reverse, in fact, as the ad states that they have cake, and that clearly implies, in accordance with the well known first law of cake "you can't have your cake and eat it too" that there is no cake available to eat. If it were not so, they would not have cake.
I rest my case.
