saudi Arabia and the United States

There is big similarity between Saudi Arabia and United States I found it when I came to the United States and lived there. Saudi Arabia has some cities on the sea and some cities not and the United States has too. For example, the cities in Saudi Arabia that are in the middle of Saudi Arabia such as Riyadh, the capital city in Saudi Arabia is not located on a sea. Likewise, Texas in the United States has cities in the north such as Arlington is not located on a sea. There are cities in Saudi Arabia in there eastern and western of Saudi Arabia such as Dammam and Jeddah are on seas as same as United States has cities on seas such as Miami in Florida and Galveston in Texas etc.
I have found a big difference between Saudi Arabia and the United states in the shifts or business hour of markets. Markets and the malls in Saudi Arabia have two shifts of work every day. One of them starts from the morning until noon and the other starts from afternoon until eleven at night, so they have time of lunch during the time which is between two shifts. They close at time of prayers for a half hour. In contrast, Markets in the U.S. have just one shift; it starts from the morning until nine at night. Some owners of markets take little time to lunch and dinner, one hour for each.
