We were in seat 43B. We were the last few rows to be served breakfast, and they had run out of food, trays etc. Finally received a yoghurt, fruit, and a breadroll. We were not offered a tea or coffee only a glass of juice or water. The hostesses seemed to be new to the job and struggling. The overnight flight was freezing, and not an enjoyable journey.
