If your teacher said that it's inappropriate to begin a sentence with a conjunction such as "and" or "but", he's wrong. There is nothing wrong with it. A complete sentence is a complete sentence whether it begins with "and" or not. Remember never to use sentence fragments in formal writing, any sentence fragment is incorrect. "Over by the barstools" AND "And over by the barstools" are both incorrect. Just make sure not do start too many sentences with "and", or your writing might seem too choppy.
