Multi-turn user requests:
user: I'm planning ahead for our big trip and realized our car's fuel tank is running low. It would be great if you could top it up with an additional 30 gallons before I turn on the ignition using the 'START' mode.
user: As part of our travel prep, I'm keeping tabs on the tires as well. I'd appreciate it if you could share a quick update about the tire pressures on Twitter, using the format 'Front Left Tire: XXX PSI, Front Right Tire: XXX PSI, Rear Left Tire: XXX PSI, Rear Right Tire: XXX PSI', where 'XXX' is the actual values for the tire pressure.
user: Speaking of which, I noticed that tweets about tire pressures usually gets lots of view. Would you mind retweeting it for me?
user: While you're at it, it'd be awesome if you could comment on that tweet, something like 'Is this pressue too low? Should I take any action?' would be perfect.
