Only in America people say "Sir" to server in Resturant or give respect to blue collar work. This is the heart of American society. If you do not respect work you haven't learn from america or its culture. I don't see anything wrong working in Gas station or resturant its just a work. As a matter of the fact, they are highly profitable business with as much as 40%-80% profit margin. Without working and learning the business how would you own them? Mr. pres. of Nepal ->wake up. If you do not like these people who work in gas station or resturant then do not use their service. Period
