What I mean is there's no sign of any customers!

It looks like a bar on the outside, but it's really being used as a criminal hideout, isn't it?

For instance, everyone is doing drugs,

then they lose their heads, get into an argument, and end up killing each other.

...Why are you damp?

Me being damp has nothing to do with this.

Now that I think about it, you're the oddest and most suspicious one here.

Even though there's a dead body next to you, you're just sitting there all relaxed.

Oh, so you're going to arrest me for the crime of sitting here all relaxed next to a dead body?

...Even if you're just a customer, it's still strange. Normally, for something like this, you'd report it or run away...
