EMBARRASSING A PASSENGER

My granddaughter and myself traveled on the 12th of Jan on the 21:55 flight M460 from Cape Town to Lanseria.<br> I prebooked our seats at the emergency exit. Just before take off one of the flight attendants came to us asking my granddaughters age. She told him she was 17. He then said well you then not suppose to sit at the emergency exit, you should be 18. I told him that they then should not have allowed me to prebook her seat. They knew her age when I did the booking and on check in they also had no problem. But he just carried on and on, saying he does not care if we prebooked, she cannot sit there. He had such a bad attitude and spoke loudly for all the other passengers to hear. She is a shy person and this was extremely embarrassing for her. I was furious with this person. (He was the bigger one of the 2 men flight attendants that were on duty). <br> Only today when I booked another flight did I notice that you actually only have to be 16 to sit at an emergency exit. So his rudeness was pointless. What did he want to achieve with his bad attitude. He embarrassed us both and spoiled what should have been an enjoyable flight.
