The 'Heart Attack Grill' Experience

It’s definitely a weird way to market a business, but it is obviously working for them. Most companies are trying to back down on the amount of fats and high calorie meals, but the Heart Attack Grill is doing the complete opposite.  A man has recently suffered a heart attack, while eating a “triple bypass burger”, slightly ironic. Their quadruple bypass burger has around 8000 calories in it, which is more than what most people should be eating in a whole day. It’s a 50’s style diner, but with a twist. When you walk in you are given hospital gown to wear, the waitresses are wearing nurses costumes,  and the owner walks around in a doctors gown and has a stethoscope. They even have wheelchairs to assist the customers who are not able to walk out of the building after eating the excessive calorie filled burgers. They even have a special offer for customers who are over 350 pounds;they are allowed to eat unlimited bacon burgers for free. Even though customers know what they are getting themselves into upon walking into the burger joint, I would never want to own a business that could land their customers in the hospitals. Do you think this is a good way for a business to market themselves? Should the business be held liable if someone is to have a heart attack from eating there?
