I would most likely calmly tell them that I am a citizen of the United States too, and I demand a table. If they still will not seat me, I would probably calmly exit the restaurant and find somewhere that will. That's on them for not seating someone because of their race or culture.
Hope this helps~!

Answer:
 to solve problems and make life easier for humanity
Explanation:
The main basic purpose of nearly all technology is to solve problems and make life easier for humanity. This I think would be considered the basic purpose even thought it is very simplified. Technology also has the purpose of helping humanity expand our capabilities by allowing us access to information and abilities that would otherwise be considered impossible. These abilities and knowledge greatly increase our knowledge allowing us to pursue more complicated endeavors.
