How does Leila get caught out at night on her birthday?

The young women's plan is going off without a hitch when suddenly, Hakan appears at the restaurant where Yasmeen, Leila, and Amal are celebrating Leila's birthday. Hakan makes a big scene, calling the young women sluts and yelling at Leila to come home with him. The manager comes over and asks the group to leave, at which point Hakan takes Leila out of the restaurant and forces her into his car.
