What: “We only have one mop.” bronze trophy
When: During Year One (beginning of the game)
Where: Rubacava
In Rubacava, you'll only find two souls to converse with. One of them is Celso, who is the custodian of the rest stop found at the top of the stairs. Manny will know him from a previous sale attempt. Due to his recent unemployment, inquire about getting a job around Rubacava and he will eventually speak this line.
This is missable. Make sure to ask of employment before handing the logbook over to Celso, solving his problem that he speaks of when you question him.
