Samuel swaggeringly raises his glass in front of Katrina. "Get me another drink!"
His arrogance makes Katrina flare-up in a fury.
Last time, Samuel trapped her and pushed her into Melvin's room. She hasn't gotten even with him yet. Now, while she's on duty, he tries to spite her and refuses to let her leave.
Katrina struggles to contain her anger and glares at Samuel. "I'm here on official business, Samuel! I don't have time to waste on you!"
"Ah? Official business? What business? Attending the guests present?"
Samuel continues to shove his glass to Katrina in a haughty manner, insisting snidely, "Go and get me another drink! Didn't you hear what I said? Do it, or I'll complain about you!"
The commotion naturally draws more and more spectators. It feels very unpleasant to be surrounded by a crowd of onlookers.
Moreover, Katrina is the person being insulted.
