WHY do restaurants give mint gum to customers?

Contrary to what you might think, restaurants offering peppermint candy or gum after a meal are not trying to imply that you have bad breath. The intention is actually to aid in digestion. Peppermint has a calming effect on the smooth muscles of the gastrointestinal tract and can help alleviate symptoms such as heartburn, bloating, and overindulging. The restaurant's ultimate goal is for you to leave feeling satisfied and comfortable after your meal.
