Klaas was made enthusiastic by his uncle because he was allowed to ride along on the truck from the age of 4. After his military service, Klaas started working at the former paper company Van Stralen in Geleen at the age of 19. First as a warehouse employee, but as soon as he got the chance, he got his driver's license.

A few years after B.Enyounés (for colleagues Younes) came to live in the Netherlands he started sorting plastics in Sittard. Soon Younes got his forklift diploma and then became responsible for the (press) machines. He has no ambition to get his truck driving license, he feels perfectly at home in the plastics hall.
