This exceptional hint originated on an airplane. In its bathroom. Here's how the story goes: Recently, a traveller on a particularly puny plane noticed that the scent emanating from its one bathroom smelled pleasant, but not air-freshener-y. After a bit of investigating, the traveller found the source. Four tea bags were hanging on the back of the bathroom's door. The flavor? Good Earth Spice Tea, but any pungent scent of your liking would do. Great idea for sweetening the air in a small space, no?
