A waiter passed by, a tray of food held high.
The tray she held she put down on the bed for lack of table.
A waiter went by with a tray holding a bright green drink.
Within was a tray holding some scattered objects of apparel.
Then he returned with a tray holding the wine and goblets.
Then she was gone, empty tray held loosely in one hand, closing the door firmly behind her.
Each tray held an array of ten to sixteen tiny buttons.
She pressed the button, heard no sound, and waited with her tray held level at shoulder height.
Her tray held a bowl half-filled with cereal, and a cup of black coffee.
A baking tray could hold salt but have more of it open to the air, which would help for more moisture to be removed.
