Person2:Why would I spy on you ?
Person1: Because I am your competition which you know perfectly well , or you would not put up that sign just around the corner .
Person2:The entrance to our store is around the corner . And there ' s no other way of saying that . It ' s not the name of our store . It ' s where it is . And you do not own the phrase around the corner .
Person1: What is that ? What are you doing ? You ' re taking all the caviar ! That caviar is a garnish ?
