In some ways I wish I shared your attitude of not caring about the other guy as long as I get mine, things might be simpler if I could say "screw you" that easily, but I think my life would be poorer in many other ways if I did. Perhaps when you get past your early 30s you'll gain a bit more understanding of the others we share this planet with, some of whom don't have whatever advantages you do, and mellow out a bit. There are more important things in this life than forcing someone to give you nine airline miles for a Chinese take-out lunch, when the 30 to 50¢ he pays Visa for the privilege is more than his margin on your meal.
