For a lifetime I remembered a colleague's story about designing a puzzle. They brought him a huge painting-puzzle. While they were taken from the reception to the workshop, everything was dissipated. We gathered the whole group for two weeks. When they gathered, there was no fragment. My hair is scared, what to do? They went to the advertisers, who for a lot of money printed and cut out the necessary piece. The customer comes to pick up. He looks around and confusedly says: and I didn't have one fragment here - the children were still lost during the assembly. My friend said he almost fell when he heard it.
