It's not clear what the problem is. Is it that the mic quality is not good enough for an AI? Is it that the AI is not smart enough? Is it that people generally don't like AI taking orders? Is the latency not good enough?
Or is it that people prefer to preorder on the phone instead and pick up?
After years of effort, I'd say that most of the simple non-AI issues were examined.
Lots of videos on TikTok illustrate the problem.

How much is it because they were still too early?
Would they do significantly better with a model like Claude 4 than I’m guessing something worse than GPT3.5?
Once you incentivise people to use AI by unbundling the costs of using humans vs using AI, you will see a lot of people fall in line. Although legally I do not think it will be an easy implementation. I am sure a lot of people already order via web or app nowadays.
