worst flight of my life

I had the most terrible experience on Air Mauritius- I asked for seats with more legroom and was given seats in row 5 just for the flight controller on the ground to start shouting at everyone in the row to move because a family with teenage kids wanted to sit there- I am a paying customer! If your staff is friends with people ad wants to do them favour great but not on my account and not to humilate me!! Worst flight of my life
