Find the Hairdryer is just one of America's hotel housekeeping games. I think that the most nefarious hiding place can be the back of the bathroom door trick. Unless you close the door, you'll never guess where the dryer bag is hanging.
This is just one of many "games" is frequent hotel travelers play which also include:

Wonder if housekeeping will ignore the DND sign on the door
