for me it all comes down to manners and what parents and the schools teach the children, Simple consideration for people, waiting your turn, saying "thank you"," excuse me" and "please", and knowing how to behave in public.For instance you eat at the food court,you pick your tray up when you finish and take it to the trash.I don't care how old I am or what country I'm in, my mom would slap the hell out of me If I left my trash on a public table and walked away. this isn't about culture or "if you don't like the country leave" it's about manners, being polite and knowing how to deal with people. I don't agree with my friend simply because I don't care what these people do, it's not my job to teach them what their parents failed to do.
