Answer
The business case is not simply 'answer messages faster'. For a weather-sensitive local business, the assistant should make every enquiry more complete by covering rain, sea conditions, tour changes, transport delays, operating hours, cancellation options and what customers should bring.
The assistant can explain the business's own weather policy, link customers to the latest official forecast, and separate a provisional update from a confirmed cancellation or closure.
It should timestamp weather information, avoid presenting forecasts as guarantees, and escalate swimming, boating, medical or emergency decisions to official authorities and trained staff.
The useful model is an Own The Conversation Digital Twin: approved business knowledge is organised once, then used by the assistant and the public information layer.
A useful result is fewer confused customers, clearer rebooking decisions and a visible record of when each update was issued.
