During his student years he worked with his uncle. He was engaged in the installation of windows, and I helped him to dismantle the old windows. And here he told me one story that happened to his colleague (let it be Vasya).

Coming, therefore, Vasya on the object, the house is new and the homephone does not work. He climbs up to the second floor, calls the door, opens the housewife, he appears to be an installor of the company "Moscow windows". The first thing to do is to inspect the window holes and overmeasure the frames, as freezers sometimes make the wrong measurements and it makes no sense to unfold the entire tool. The windows in the house are almost on the floor. He enters the room, approaches the hole and automatically bends to look down, and through his shoulder a huge bag with a tool (perforator, lobnik and other shit). The bag overweighs and he falls out on the street. Fortunately, he doesn’t break anything, goes up the floor again and knocks on the door. The dialogue:

Who is?

Manufacturer of the company "Moscow windows"

A few minutes of silence and steps around the apartment (apparently looking for Vasyan in the house) returns, opens the door and in stupid silence starts back.
