premise: The front of the cafe must remain free of trash if customers are to be enticed to enter.
hypothesis: Customers are looking at the door of the cafe.
explanation_1: Customers don't need to be looking at the door to notice trash.
explanation_2: Just because the front of the cafe must remain free of trash if customers are to be enticed to enter, doesn't mean customers are looking at the door of the cafe.
explanation_3: It cannot be assumed that people are looking at the door of the cafe.
