In a campaign that's been going on for more than two years, Ricola has been rewarding people for having their cough drops handy. How are they conducting this contest, you ask? Well Ricola has hired "mystery coughers". These marvelous people go around to crowded spaces and go into a coughing fit (I'm not kidding). If you offer them a Ricola cough drop, congratulations, you win a prize! And if you don't have a cough drop for them, well, then you just get coughed on.
