Coppi is almost describing a flight a friend of mine did to Marrakesh (I believe it was there) not too long ago.
On speaking with Casablanca they were told it was closed due to an air show, they asked if it was NOTAM'd as being closed, to which they already knew the answer (no it wasn't!). The continued, and landed as part of the airshow after a short delay.
Coppi, you need to get your facts straight before jumping to conclusions based on you listening to a little bit of ATC.
