McDonalds specifically published something about how AI made their customers revolt and gave them enough loses by overpromissing stuff that they would remove their bot. I have no idea how widespread it was, but I think there isn't a bot anywhere nowadays.

I tried finding it as I have seen the meme a few times. But there doesn’t appear to exist either in the app or on the website. There is just a faq and a normal web form to submit questions and someone will get back to you.

Although I guess they may have taken it down.

Edit: I have tried it with chipotle’s chat bot and they appear to have disabled it and it just says it can’t code as a response.

It's from LinkedIn so my guess is it's a US pilot program or specific to the Maccas app.
