Bham Gal, NOTHING gives a person the right to be rude for no reason. No matter what their issues are, how bad their day is, they do not have the right to ruin someone else's day with their rudeness. I've worked retail and NOTHING is worse than adults who do this. And they do it because they got away with it as a child. And as an adult they get away with it because "the customer is always right". Rude children are likely rude because their parents are rude adults. "Maturely an compassionately process perceived rudeness" basically means "be a doormat".
