I ran into this by accident. It's very interesting. Do you feel the restaurant should be sued? I think so and this is a real victim in this age of victimization, I think.
Fast food contain too much saturated fats, to much sugar and sodium. There is nothing nutritious in fast food, it is loaded with calories. Eating fast foods too much will destroy your health.
The restaurant should be sued because they know what they did and it was a well thought out thing. Fast foods are not safe. It is better to always cook safe food at home to eat.
Fast food if you eat it in excess or too often can be quite harmful to your health because of the amount of chemicals and additives it contains, if you eat it from time to time I don't think it can be a big problem, but if your consumption is frequent it can cause overweight, high cholesterol, heart problems and much more.
