Whenever you find yourself angry, excuse yourself from the situation.

The more emotional you feel, the less rational you’ll think. Learn to recognize your personal warning signs of anger and remove yourself from the situation before you lose your cool. This may mean saying, "I am not willing to talk about that right now," or it may mean walking away.

For example, charging more for a first-class seat would not be price discrimination. Charging different prices for the same kind of seat, either first-class or economy, would be price discrimination.
