If I recall correctly, they did an interview with AP or Metal Hammer back in the 00’s explaining that they weren’t a Christian band, they just liked how brutal the story of Cane and Abel was from the Bible and used it as a framing device.
Correct me if I’m wrong, though; I haven’t looked them up in over a decade.
I swear I read somewhere that there are parts of Europe were tipping isn’t required, but if you want extra good service you’ll tip before being served if you want good attentive service.
Please correct me if I’m wrong, I can’t remember where I read it.
