Explanation:

The phrase Always Be Closing was popularized in the 1992 film, "Glengarry Glen Ross" starring Alec Baldwin, Al Pacino, and Jack Lemmon. The movie was written by David Mamet and was based on his Pulitzer Prize-winning play. It emphasized the darker, cutthroat side of the sales industry.

In the film, an aggressive representative from the corporate office is brought in to motivate a group of real estate agents, telling them to sell more property or be fired if they fail. He delivers a profanity-laced tirade, accusing the salespeople of being timid and unmotivated. He flaunts his wealth and success.
