Know The A.B.Cs of Commercial Real Estate?

In honor of the Miami Film Festival, which starts today and runs through April 13, Fernando & I thought we would revisit a classic that spawned a few of the sayings in real estate that are still around today. I had heard Always. Be. Closing (ABC) & "Coffee is for closers" since I started in real estate decades ago, but had never seen the movie, Glengarry Glen Ross released in 1992. Have to confess, in spite of an all star cast, I am not a fan of the movie, based off of a play by David Mamet, for which he won a Pulitzer Prize. Too much whining about leads! I wasn't in real estate in 1992; where you? If so, does any of the movie ring true for you?
