Disgust flooded Peter's features, his hand immediately turning upside down to let the piece of...mush fall to the floor. Resentment and hunger and irritation and hunger once again coming to his face. "Maaaan, I told you I didn't have any Earth money."

Still, the Duck had fulfilled his end. Sorta. "Move," Said with a sigh, Peter held the door with his right hand, motioning for the Duck (named Howard--he suddenly remembered) to move aside with his left before the door frame came to life with a dim translucent glow; ripples of a brighter purple light cutting across the door frame here, then there, up top, down low, and then here again. 

Only then did Peter remove his hand from the door. "There."

There was no more sound from beyond the door, no more energy used on the other side to push it open. When the door WAS pushed open by those outside it, all they'd find is an empty bathroom...with no mints and a piece of mushy meat globed in gravy upon the chilled tile floor.
