The photo shows a sign on a red background with the Algida ice cream logo. The sign says: "AKBIL SATISI YOK. YOK. YOK." This is a funny sign because it's a pun on the Turkish phrase "yok" which means "no". The sign is saying that they don't sell Akbil cards (public transportation cards) but the repetition of "yok" is also a way of saying "absolutely no". The humor comes from the fact that the sign is attached to an ice cream stand, so it's unlikely anyone would go there to buy Akbil cards anyway. It's a funny way to make a simple statement. So the joke is that the sign is being sarcastic and is not selling akbil cards. The joke is in the repetition of "yok" which implies "absolutely no" and is a humorous way of saying "no." AKBİL satışının olmadığını vurgulayan bir ifade.
