I'd be happy to assist you today, but first I'll need to know your departure and destination locations?
I need a taxi leaving after 10:30. I need to be picked up from Sitar Tandoori and I am going to Clare Hall. And I need the car type and contact number.

{"__type": "Request", "service": "taxi", "values": ["arrive by"]}
When do you need to arrive?
