Since filling up at the gas pump is always so much fun, now you can fill your guests up (with liquor) via your own Bar Petrol Pump.
Fill it up with the beverage of your choice, pull the handle and fill a glass up. The pump holds about 30 ounces, so you can just about put that entire quart of malt liquor in there. Although, by the looks of that hose you may not be able to get that glass filled before the liquid gets warm. They have it for £17.99 (about $35) at Drinkstuff.
