Generosity is one of the most positive characteristics that many Saudis have in common.  Some believe that part of being an Arab is that hospitality and exaggeration in welcoming guests  are serious duties. The best and safest way to show your generous side that has been hiding for a long time is to invite your friends and guests to a lovely dinner.   Breakfast or lunch will not work due to the Saudi schedule that starts from 1 pm (although I know some people will wake up early for free food).  When it comes to eating, Saudis like to enjoy every bite and make sure that they taste everything on the table;  all of this is time-consuming; therefore, dinnertime is the best time for Saudis in case they are planning to spend more than two days eating.
For newbies in hosting dinner parties, I just want to say that pizza will not work…it’s either a whole animal; usually lamb or some certain type of herbivorous mammal or nothing at all.   Make sure there is dessert after dinner, and yes fruits can be dessert and for extra street credit serving tea after words will be the best option.
Dinner invitations will always be a part of  Saudi culture that leads to bonding amongst each other, making new friends, and solving many problems… but seriously, who doesn’t like free dinners?
