The house next door...or how to NOT build a house

[Toolmaker51]

About 07:00 I let the chickens out and suddenly heard water running from The Tar Pit. I looked over and a worker had just drilled a hole in the rain gutter to let the water out. I looked down the length of the house, sure enough there are no downspouts (roof drain) anywhere. Who installs rain gutters with no drain holes?

Very simple. This age of specialization divides contractors into ever smaller classifications "Oh, you also wanted downspouts?".
Or crew supervisor claims, "In this multi-step process, we gutter first. Our scientific quality test verifies no leaks".
He also might work 'our exclusive technology' into the phrase.
