Sam to the rescue!
I guess it's time I head back to my ship. How much do I owe you?
Nothing. I'm not exactly set up to handle customers with money.
This life station's funded as part of the terraforming effort. I don't even have a system to accept payments. So don't worry about it.
But your time, the supplies I used up. Winston, I must owe you something.
Florence, a captain is always supposed to side with his crew, but I really have to support the Doctor on this one.
