Self Check Out...With Champagne

I don't know if you've noticed this but, 8pm on a Friday night is a busy time at the supermarket. This means lines. Lines at every register. Even the 12 items or less register has a line because of some bat shit, crazy lady with 35 items.
Listen. The line waiting stops here.
You have somewhere to be. And you have 3 ice cold bottles of champagne getting warmer by each passing, line waiting, minute.
This, my little grasshopper, is what the self check out is for.
You swipe the bottles. You swipe your card.
They quickly come over to make sure you are of age.
And you are out of there! You are in your car and on the way to an undisclosed location with 3 bottles of COLD champagne and not a second to spare, to do a little self checking out of your own.
