Helen went to Big Stan's Diner for lunch. The restaurant was very busy and service was slow. It took 20 minutes to get a seat and then 20 minutes for the server to take her order. When she asked for a refill of her drink, the server rolled her eyes and stomped away. When Helen left, she posted this on her Facebook page: "This is the worst restaurant ever. The server was so rude to me! Do not go here!" The disgruntled customer tagged the restaurant's Facebook page in the post. The post received a number of likes and shares. The following week, Helen walked by Big Stan's and it looked just as busy - there was a line out the door. Stan (owner of Big Stan's) saw the post and called his lawyer. Consider the issue of whether the restaurant could successfully sue Helen for defamation
