Being denied a sale in a single store is nothing compared to how iranians would treat an american trying to live on thier soil. Have you seen the videos of thousands of iranians screeming in unison, stringing up fake american dummies, beating them with sticks, stoneing them, setting them on fire and burning the american flag in the streets? For the most part we live with you in peace over here,we wouldn't string you up or cut your head off with a knife or burn you alive but you are appaulled that someone doesn't trust you here?
