One day, the hair found in the dish of one of the visitors exasperates the scrupulous and disciplined chef Haji Hassan. The angry chef immediately convenes his team and announces their punishment. The
next morning, all the employees come to the restaurant with their heads shaved. When Mehmet was left without hair as a result of this punishment, a scar in the shape of the letter "V" became visible on his head, resulting from an accident at an early age. This sign, which means "seven" in Old Turkish, attracts the attention of the master, and he gives him the nickname “7 Mehmet”, which will never be erased from his name. This is how the story of Mehmet 7 begins.
