Don't Judge Your Fellow Flip

I had a friend who went on a Orlando vacations 2 years ago. The place is rich in diversity as almost all the nationalities in the world are present on the neighborhood they stayed in. One afternoon after they had their day's itenirary they decided to sit down for a coffee. My friend was also waiting for a friend and since he was 30 minutes late he decided to go out of the place and made himself present on the streetwalk. Minutes later he was asked by a group of tourists who happens to be his same nationality, asking to take their picture. He did do the favor, but after that he heard a nasty remark which he understood (spoken in his native tongue) - he replied back to them making their faces red! They learned that my friend’s nationality is same as theirs.
