She is shaming and belittling him. Tells her viewers as she films him that he has ordered food and that he is a "waster". Opens boxes of his food to show the viewers and mentions the drink has 600 cals, followed with a quick "just kidding guys" cause she is full of tit and knows it. Then she continues to berate him and says he is "stuffing" his face with the food. No it's not the argument of the century,he will get over it. One day though, filming the supposed love of your life so you can get some more views after a while you may find you don't have a victim to use any more and he's walked out of the door.
She talks to him like tit, spends as much money, whenever, wherever she wants. He's a grown man, works a real job. She thinks she will her up her views with this and get her undying support from a bunch of very strange obsessed fans. Thing is though, shut thy gob for once and try reading his face before you tell people you were not shaming him, but actually reading someone might take effort and care and a bit of intelligence.
