Percolator

“Uh, yes…” said the militis, befuddled. “Well. This first hose here is a
stimulant, and this second one is a slight sedative, for agitation. This next one
offers focus, and then this fourth is physical relaxation. Finally, that fifth one
there on the end is an appetite suppressor. For very long meetings, you see.”

“Excellent!” said Ana. She sat, fumbled for the stimulant hose, popped its
black nozzle in her mouth, and gave it a mighty suck. The brass percolator
burbled and warbled; then she sat back and exhaled, releasing a roiling cloud
of thick steam. “Thank you. We shall wait in comfort, then.”

The militis departed, shutting the door behind him. I watched guardedly
as Ana took yet another outrageous suck from the stimulant nozzle.
“Are you sure you wish to be doing that before our meeting, ma’am?” I
asked.

“Oh, it’s all very mild,” she said, her lips blooming steam. “These
reagents just give your mood a slight nudge. They’re not real moodies, like
the ones I prefer. Here. Pass me the relaxant one. Let me give that a suck."
