Genuinely curious, what could an LLM even do for an ice cream shop? Checkout already takes less time than scooping a cone, and it's even quicker with cash. Maybe it could surveil the customers and employees? But I think that will lose you more customers than it gains.

Generally I would expect the ROI to be negative, like we've seen with most corporate AI projects, so yeah any ice cream shop that didn't invest in "AI" is going to come out ahead of one that poured money into the pit.
