Are You Buying It Back? An Analogy!

You are in a restaurant and ask for a glass of wine. Your waiter brings the glass and a full bottle of wine to your table, places the glass in front of you and starts to fill the glass. You are gratified when they fill it right to the top.

You are very surprised, however, when they continue to pour! The wine overflows onto the table and then splashes onto the floor. The entire bottle has been emptied, but the only portion you can consume is contained in the glass.

What would you say if the waiter charged you for the full bottle?
