Quote context

[...]

- Good morning, friend.

- Where'd you get that water to make coffee?

- I just took it out of there.

- Oh, you did, did you?

- We didn't carry that water up here for you to make coffee, see?

- I'm sorry. I didn't know water was so hard to get.

- Well, you know it now!

- I'll fill it up for you.

- What's up?

- Well, I caught this guy stealing our water. Next time you try that, I'll let it out of you through little round holes.

- I thought perhaps I was among civilized men who wouldn't begrudge me a little fresh water.

- Who's not civilized?

- I could easily do the same for you. It's not settled yet who'd come out on top.

- This time, I took it. Thanks for your kind attention.

- If I were you, stranger, I'd pack up and go while the going's good.
