It's at the 21 second mark. In the background, we see the blurry image of a single person who has both hands on the table and is staring down at her tray.
What is going on there? Is she experiencing an epiphany- "oh my god, I am sitting here all by myself at McDonald's, about to eat greasy, salty junk again? What has gone wrong with my life?"
"Why am I sitting here with this food? Why didn't I do what I usually do- use the drive-thru, then pull over to a parking space, consume my bag of overpriced trash, and then have a good cry, like I usually do?"
Or is it ""wait, didn't I order a hamburger? Why isn't it sitting in front of me. Maybe I didn't order it. I don't really remember. I often don't remember things I did two minutes ago; it might have something to do with a steady diet of empty carbohydrates, salt and fat and not enough actual food. Oh well- I'm not going to waddle up to the counter and order that hamburger now. Not in front of these other people. And I can't just drink my not-milkshake and eat my fried potatoes and then use the drive-thru on the way out; the girl who hands me my bag might recognize me. I'll just finish up here and then hit one of the other three McDonald's I pass on the way home."
Whatever it is, it's really sad. This blurry woman in the background needs help. The kind of help she won't get from a Health At Every Size "life coach/nutritionist" on Tiktok. The kind of help she won't get by ignoring nutrition advice from an ACTUAL doctor. Certainly not the kind of help she'll get from consuming warm trash from McDonald's. I suggest she seek medical attention, including therapy, to find other ways to cope that don't include clogging her arteries or seeking to dull the pain with "comfort food" that leaves her depressed and addicted. Good luck to her.
