Buy a feather and use it.

You count your chips and throw some of them into a tiny metal chest right next to the feather's box. Then you reach for a peacock feather, and admire shortly the scintillating colours flickering in the light of the lanterns and torches, lightening the corridor.

Manoeuvring the feather is a bit more difficult than you thought, because the light and long tool bends and bows this way and that way, but you soon get the hang of it. Two bystanders who were chatting with each other turn silent, as you approach the woman. Apparently having somebody tease the naked body is seen as some sort of spectacle. The question if, of course: which body part do you aim at?
