When Patrick Stewart's character Mace is putting the dummy back in the closet, he straightens his clothes. During the shooting of Star Trek, Patrick Stewart did this so often that it came to be called the Picard Maneuver.
Andi Travers looks for something to hit the "intruder" with during the first "drill" she witnesses. She looks like she is reaching for something when the viewpoint changes. You can see the handle of a gold club that she is holding. The viewpoint changes back to the oriGinal one and we see Andi reach for and pick up a golf club (the one she was just holding).
Mace refers to "Chateau Margaux Blanc De Blancs" when speaking of a wine. Chateau Margaux is from Bordeaux, and "Blanc De Blancs" would be from Champagne. Corrinne Menzenoupolos (owner of Margaux) does not make any sparkling wine.
