The title character in "A Man Called Otto" (Tom Hanks) is described as a "nasty bitter man" by someone he encounters, however, what others see as rude is really Otto expressing his inability to suffer fools gladly. He considers most folks "idiots" because they simply fail to prove him otherwise.
Otto is a man who goes by the book. If he wants 5 feet of rope, then he should only be charged for 5 feet of rope, not 2 yards. If someone does not follow the rules, like locking the gate in their neighborhood, he calls them out on it. His pragmatism makes him an oddly likeable curmudgeon; Otto is a man who abides by the rule of society and expects others to do the same. His inflexibility is not obstruction, it is going by the book to ensure equality and fairness for all.
