书面表达One possible version:

Hello,everyone.Many people enjoy eating something inmovie theaters.As far as I am concerned,this behavior can bereally annoying.I remember one time I was at a movie theater inmy neighborhood.As I walked toward my seat,the dirty floor inmy row almost made me sick.My mood was ruined at once,andlittle did I know things would get worse.The viewers sitting nextto me started eating chicken wings or something else right afterthe movie began.The noise of those plastic bags and the smell ofcertain foods made it hard for me to focus so that I missed mostdetails of the movie.Therefore,food should be banned in movietheaters.

Thank you.
