I just read this whole thread. Breaking news! Person A was rude to Person B.
OP has two options:
1. Make a (literal) federal case, be busy with it for months, and get more and more upset as time goes by without getting free flights for life (or whatever "compensation" he now expects for this trauma), or
2. Shrug and say "that's life, sometimes people are jerks" and move on like a mature adult.
You tell me which one will make you a happier person.
