Opinion to the studio!

Write in the comments how you would characterize a person who bought a truckload of sand for his plot to tidy up the children's area, garden beds, and paths... He dumped the sand on the plot and while working, he accidentally found a gold chain weighing 200 grams in this pile. It would seem like a treasure! But the man called the sand delivery driver with a request to take this sand back along with the find and bring another load, because he only paid for sand, and here there is gold. He only needs sand!

I have no doubt that the sand delivery driver will gladly fulfill the request and buy the gold at the price of sand. But the question is different))
