I only drink red.

At the end of the night, some of both bottles remain.

What’s a subdivision to do?

Before I mention the solution, let me mention the price.  At $1000, I’m not necessarily suggesting you run out to buy this for your favorite oenophile.  But the Skybar WP1000–with its space-age ability to simultaneously store, chill, pour, and preserve three bottles of wine–is definitely fruit for fantasy.

I suggest you split the cost with your neighbor.
