Kumar was very excited for his Valentine's day but at the same time he was afraid about the demands of his date.

All was going good, but at last they ordered wine, waiter offered x and y unit glasses, here she got him, she said "I will drink only z unit, it's a crime not to eat a rare steak without a good glass of red wine".
Now to get the z unit out of x and y unit of glasses, Kumar starts shuffling wine from one glass to another, as it will impress her, he had to do it quick, he does't want to get embarrassed by calling for other glasses, or making other excuses.

Guess how he managed to serve the wine.
