Staff were not friendly at all, very dry. There was chaos prior to boarding as people had to guess where to go and they were just standing there until they finally called the group numbers . Food was not that good either, flight attendants didn’t come around for drinks on a 9 plus hour flight to make sure people were hydrated. Again staff was not friendly.
