The first ChiggerBurgers were sold by a Ferengi named Logi from a single stand in Ferengi year 14305. It was rumored that passers-by who refused to purchase Logi's ChiggerBurgers ended up as ingredients.
By the 24th century, ChiggerBurger Emporium restaurants were located on every half-block on Ferenginar. Additionally, ChiggerBurgerCorp would home deliver a daily supply to their customers -- whether they had ordered any or not.
The slogan for ChiggerBurgers was, "They're the Krunchiest burgers in the Galaxy!" An alternate advertising slogan -- "ChiggerBurgers... Good" -- was supposedly used by genetically engineered insects who would whisper the phrase into sleeping Ferengi's ears. (DS9 reference: Legends of the Ferengi)
