Multi-turn user requests:
user: I'm planning a road trip from Rivermist to Stonebrook and would love an estimate on how far this journey will take me.
user: Great, now that I know the distance, please check if my current fuel level can handle the journey or if I need a refill.
user: Ah, it looks like I might need some fuel. Could you go ahead and fill up the tank with 30 gallons of fuel so that I end with 40 gallons?
user: Perfect, it's ready!
user: Oh one thing I missed. Let's get the vehicle ready by starting the engine, please make sure everything's in place.
