Under the guidance of the staff, Marvin and his companions, carrying a motley of snacks, arrived at VIP Room No. 4.
Every theater has a high-level lounge independent of the main hall, which not only offers a broad view but also ensures that one need not worry about being disturbed by others. If privacy is needed, one can draw the curtain to block the view of others.
Marvin, of course, had no need for privacy, for this time, they had to let everyone know they had arrived, openly and honorably.
Sneaking around, wouldn't that be acting like a thief?
If others didn't know they had arrived, then what was the purpose of their coming?
