What do you know about professionals?
I was told by a hairdresser I knew that a master named Said came to cut his scissors. This master wraps in different areas and makes raids to hairdressers. After that, the knives stopped cutting normally.
The hairdresser has nothing to do - takes the sealed scissors and goes to Voronezh (200 km). This is shown to a verified master. He looks at the scissors and says only one phrase:
Oh that said. And the marriage.
