Back at the table, Walther lifted his glass to suggest another drink. She shook her head, explaining,
"Olndrptd."
Spelled out with his Manual, her explanation was:
"Only one drink is permitted."
And, after Willy's brief orientation, this was understandable: Nothing could disrupt the perpetual entertainment cycles more easily than excessive drinking. A tipsy person was not a good customer for other leisure-time activities. Therefore, permit only one drink to a person, and charge enough for it so that the liquor monopoly would get its fair share of the entertainment expenditure. As Willy would say, it was just good business.
Maria touched his hand to signify it was time to leave. Walther took her up to her room on the 32nd floor, and they watched two musical comedies en route on the elevator pay-as-you-see television screen.
In front of her door, Maria lightly touched the back of his hand with her fingertips. She said,
"Thyfrwrdrftm."
Walther knew she was thanking him, but from force of newly-acquired habit he reached for his Manual.
She laughed, shook her head and translated her own words by raising up on tiptoe and brushing his lips with her own.
