Multi-turn user requests:
user: I am planning a road trip from Rivermist and I need to know how far I will be traveling. This would help me ensure that my car is sufficiently fueled for the journey.
user: The destination is San Francisco.
user: Given that the trip spans over 980 kilometers, I have to make sure the fuel tank is full. I have a 30-gallon drum handy. Would it be possible to fill the tank for me after converting the volume to liters?
user: Now that the tank is completely filled, I'm keen on ensuring that the engine starts without a hitch. Could you help me get the engine running, ensuring it's all set for the long journey ahead?
user: Before I set off, I want to share my travel excitement with friends on Twitter by describing the wonderful places I'll be exploring during this adventure. Would you be able to post a tweet saying 'Excited for the trip!'?
