Bars frequently provide snacks for their drinkers to enjoy, either free or at a nominal charge. These snacks invariably contain large amounts of salt. Why would providing such munchies be advantageous to the bar's profits?
What will be an ideal response?
An increased intake of salt will stimulate the thirst center in the brain, and will stimulate the person to want to drink more fluid to correct the imbalance. In order to excrete the excess salt, the person will also lose a large amount of water. As the bar is providing items to drink at a profit, it will do better if it can maintain the thirst of its patrons.
