Cinemark review: cell phone use during the movie

I have been to the Cinemark In Evanston, IL, several times and not one-time have I seen employees checking on people to verify if someone is using their cell phones during the movie which the manager stated they do. On December 27, 2019, a young woman and an older lady were told politely to shut her phone off by a person the same row. I was sitting on the back row. The young girl did that for a short time & proceeded to turn her phone back on to go shopping and was not paying any attention to the movie. I then explained to her that the light from the phone is blaring in my eyes & to please turn off the phone. Again, she did that for a few minutes and put it back on. In the meantime, her Mother kept going in and out of the theater several times. (Bladder problem or waiting to see if another movie is ready to start to watch that for free.). Then they started talking & I asked them to be quiet. The mother started yelling at me & I said they were being very disrespectful for patrons who paid money to see & hear the movie and not paid to hear them talking & using their cell phones. The Mother left the theater and complained to the management and then the management asked me to leave the theater because the Mother stated I was being a threat to their safety. I refused to leave because I was not threatening them and I was not in the wrong & told management they can talk to me when the movie is over. (which was done). They told me to contact them instead of the patrons when this problem occurs again. I go to the movies often and this happens all the time and management does nothing about this problem. There is a serious addictive problem with some people who use their cell phones all the time while driving a car or at a movie theater and something needs to be done to prevent this issue.
