Say, "Yes, that is indeed my rifle, this lad here is a thief, it seems.
Anyways, thief, I said I was going to 'borrow' the money because you were under the impression that I had none left. I choose whichever words would calm you down in the spur of the moment.
Now, please just stop shouting and let's continue going. We'll soon find out if it's actually a dead end or not.
And, um... Mr. Johannes? If you could come with us, I'll explain it to you on the way, why he has my stuff and everything.
I apologize for all these misunderstandings thief, but I intend to treat you to the brothel, I've hopes that you'll be in a better mood and give me my clothes back."
As this things seem to be about to explode, if you deem my speech wouldn't be enough to calm them down feel free to cut my speech short. I wrote it all hoping it wouldn't come to violence, but even I can see where this is going.
