Sound of Music

What’s up with the scene in the Sound of Music about the pink lemonade? Everytime I see the movie that part just seems odd. It’s Max, Captain Von Trapp, and the Baroness sitting around talking about something (I forget now) and constantly interjection comments on the pink lemonade. Does anyone else ever think that’s a weird scene?

I always figured it’s because the Baroness and Captain Von Trapp are supposed to be these sophisticates, and instead of drinking wine or whatever cocktail, they’re given wholesome pink lemonade.
