First and last flight with this airline

Just boarded my first and last Ethiopian Air flight. 3.5 hours in queues, boarded 70mins late. Not a word from the staff . Incompetence from start to finish. We checked in online and it still took the check in agent 12 minutes to check our luggage through. No urgency , no professionalism. Customer lost for life. Lesson learnt . What was I thinking !!
