Idiots getting way too comfortable in theaters

I had gone to watch a movie in Pheonix marketcity yesterday. A huge group was sitting right behind me. Extremely noisy from the start and constantly kicking my seat from the back. I requested the man sitting behind me not to kick my seat twice as it's ruining my experience. He apologized and I was relieved. After sometime the kicking stopped and someone from the same group kept his legs on top of the seat which was right next to me. I mean, how can someone be so ill mannered? I looked behind and the man, without any remorse on his face looked at me and then continued watching the movie as if it's alright what he is doing. I confronted him and he told "Aapke seat pe nahi rakha hu. Aap shift ho jaao agar takleef ho rahi hai toh" My friend asked me to shift seats since we didn't want to create a scene and ruin other's experience. I feel every school in India must have a compulsory subject on Value Education and mannerisms so that we won't have to encounter such well educated morons who lack basic knowledge on how to behave in a public space.
