You could encounter someone who seems like a textbook example of a jerk, but try to be open-minded about them. Judging a book by its cover has never been your style, so don’t start now. Extenuating circumstances are at work here. Maybe they’re intimidated by you. Maybe they’re acting out because they’re worried or just have a headache. You just don’t know enough to know why they’re acting the way they are. Give them a chance and give them time.
