The Doors of Tunisia

I asked where the restaurant was when I was leaving the hotel. The receptionist said to go right and look for a yellow door like the one to the hotel. Four wrong doors later, a handsome man asked if I was looking for the restaurant. I said yes and he pointed to a different door and knocked loudly and towards the top of the door. So this signifies that he is a man. Top knocker and loud, so in the past, a woman would get a man to answer to door or cover herself. The lower knockers and softer are for women.
