Anyone who buys no-name toilet paper in a drugstore, supermarket or discounter in Germany is very likely to be holding a product from the WEPA Group in Arnsberg.

Martin Krengel, 63, is the second generation to run the family business.

He looks back on a wild year - and one in which toilet paper finally got the “appreciation it deserves,” as he says.

WORLD:

Mr. Krengel, I should ask the first question for a friend who has been fighting a bitter marital argument about it for years: Do you hang the toilet paper roll in the holder with the sheet facing forward or backward?

Think twice, marriage depends on ...

Martin Krengel:

Haha, I can relax and act as a mediator.

It's really a matter of taste.

WORLD:

Really?

In all honesty, I thought you were saying the paper had to come up front.

So don't you secretly turn the role around when you're a guest somewhere?
