First of all, let me make it very clear that, grocery shop salesman or fast-food counter boys will not speak english like you. Don't generalize people as a whole. I don't know which place you are from, I don't think that all those people back there speaking english only. Just check for a while, how many spelling mistakes, bad grammar and prepositions used improperly in your answers. Try to learn first and then start questioning others. Sarcastic comments made for others like Keralites and Tamils, don't make comments from your small personal experiences. Futile guy!!!
