Mrs. Danvers gets hit in the face with a champagne bottle (look closely!

There's a scene during 'Fathers Day' (LIVING ROOM) where Mrs. Danvers quietly delivers a bottle of champagne in an ice bucket to the nephew. She's standing in the doorway at this point. The nephew sardonically removes the champagne bottle as she looks down into the bucket. The champagne bottle hits her in the face, with sound effect, and she lurches her face back, aghast. Was this an intentional subversive gaff? It would illustrate how snotty and pompous the family is. You have to look closely to see this occur, but when it does its unmistakable. The nephew racks Mrs. Danvers in the face with the champagne bottle! Anybody else notice this moment in the film? It's quite hilarious if you have...
