My worst flight is in Indonesia, 2 hours flight from Jakarta to Surabaya. I tried to recline slowly and the person behind me kick my seat. I tried to recline again and he kicked it again. So I get up and faced him, voila, he fully reclined his seat. I'm pissed. I shout at him and pointed out he fully reclined his seat and expecting me not to. I go back to my seat and recline my seat forcefully, I don't care whether I crushed his feet on the process. This just shut him up for the whole flight.
