The flight from Manchester to Agadar with TUI Airways was the worst experience I had ever had. The Moroccan guy sitting behind me was acting like an antisocial asshole. He was loud when chatting with his friends and he put his arms on the back of my seat like a monkey wanting to play the drums. At some point, I made him aware that his movements affect my chair. He was totally not aware of - ignorant asshole. After, he behaved. So, I’m guessing that he was ashamed. And he should.
