Imagine, you get dumped out in the desert and abandoned. You have nothing but the clothes on your back and the possessions in your pockets with you(not including a cell phone) and you spend the entire day in the desert heat walking until you finally come upon a road and a 7/11 or a Quickie Mart. You are obviously very thirsty, but you don't have your tea leaves and tea pot and the store is out of water. What do you buy to drink?
A Arizona iced tea or a Lipton? Perhaps a root beer or a Mountain Dew? Or you feel you've had a very stressful day, why not have a beer?
