From the "Repo men" movie (2010).
In the future humans have extended and improved our lives through highly sophisticated and expensive mechanical organs created by a company called "The Union". But there are the Repo Men who take the organs back if the clients are in arrears which causes their death.
The main character, one of the Repo men, comes to work and sees how a manager tries to assure another client to buy an organ mentioning that Repo men are almost never utilized. After that the manager tells the mail character this:
You're killing me, coming in the front like that. l got guys trying to make sales out there, l don't need you on the floor spooking clients, all right? We want them buying, not thinking.
What does "coming in the front" mean?
