en CB01 OFFICIAL. As a construction manager, drinking is more of a normality for Mark than not drinking. In addition to his work on construction sites, during business dinners and sprawling Berlin party nights, there is always a reason for him to fully indulge in alcohol intoxication. When he tries to drive his car out of a no-parking zone in a drunken stupor one night, he is promptly checked and immediately loses his driver's license. For Mark, this is reason enough to make a bet with his best friend Nadim: He wants to manage not to touch any alcohol until he has his driver's license again.
