Dining Etiquette
A wonderful way to experience a new culture and meet locals is to be welcomed to someone's home in Qatar. And if proper protocol is observed, Qataris have a reputation for being extremely cordial and kind. It is uncommon for Qataris to host couples or families, so if you are invited to someone's home, don't assume you can bring your spouse or family along.
You won't always sit together if they want your partner or family to attend; they will make that apparent when they extend the invitation. Additionally, it is customary but not required to bring a little present (candy, flowers, or housewarming mementos) or a meal to share.
When you arrive at the host's house, you should always take off your shoes before entering the majlis, which serves as the visitors' greeting area. You should also accept anything your hosts offer you to eat or drink with your right hand. It is impolite to refuse hospitality since in Arabic culture sharing a meal is a means to demonstrate affection and forge relationships.
Just leave a tiny bit of food on your plate when you're finished, and your host will understand. And if you're asked to sit on the floor (cross-legged) and eat with your hands, don't think it's unusual. Older guests are always served first, and your host may offer cutlery to those who are unable to eat with their hands. Say "Bismillah" before taking your first bite or sip, and "Alhamdulillah" to the host when you've finished your meal. Finally, it's crucial to understand that Arabs have a very strong feeling of family privacy, therefore you should never drop by their house without calling to let them know you're coming.
In restaurants, you can use the palm of your hand to signal the waiter; however, you should not extend your index finger. Be mindful of the seating arrangement in formal settings. A Qatari will typically prevail in arguments about the dinner bill as well. If there is no service charge added to your bill by the venue, a 10% tip is appropriate.
