Looking for the culprit

"Andien! Have you woken up already?!" Lisa shouted, surprised to find her friend grinning nosily.

"Sorry to bother you, but this is a hospital. I don't want to be presumptuous but...  don't do it here please? Sir? Lisa?" Andien added politely. 

Oscar got out of bed and let Lisa go. He fixed his messy tie and shirt and cleared his throat. The man then lowered his head for a moment, his face slightly flushed with embarrassment. 

"I'm sorry Andien, it's a habit," Oscar said briefly. His head was still bowed.

"By the way, why is Mr. Oscar here?" Andien asked innocently. She turned her body towards Oscar who was sitting across from her bed.

"What are you talking about? Oscar is your boss. It's his responsibility if the employee has an accident. You should be grateful that you have an understanding boss like Oscar who's willing to take care of you in the hospital. Not all bosses are like him!" Lisa explained excitedly.
