I'm not saying that all fast food restaurants and supermarkets are like this, but some are: 1, employees of them might not wash their hands if they touch raw meat and then touch sandwich buns or vegetables or fruits (dangerous e coli bacteria can transfer from raw meat to sandwich buns or vegetables or fruits); 2, fast food restaurants and supermarkets don't always make custom orders for fear of intellectual property rights lawsuits, so if you want food well done and fun, then prepare said food yourself; 3, many fast food restaurants and supermarkets employees usually have a high school education or less, and so said employees could perhaps make or sell unhealthy foods; 4, some fast food restaurants and supermarkets only accept cash and that cause germs to be spread from customers to cashiers and to you; 5, many fast food restaurants and supermarkets rely on typical food that's delivered by semitractor trailer drivers & navigators that have long distances to travel and so such food can get more chances to be germed; 6, vegetables and fruits usually aren't cooked (if ever) and thus they might have e coli, and many meats aren't inspected at 160 degrees Fahrenheit and thus they might have e coli also; 7, many fast food restaurants and supermarkets get people to sign statements that prevent lawsuits for contaminated food; 8, many fast food restaurants and supermarkets employees don't know the Heimlich maneuver, and so they can't save you from choking; 9, many fast food restaurants and supermarkets sell foods that have chemicals put in them to make them addictive so people will spend more money to purchase more foods for more money for those fast food restaurants and supermarkets and so people will get fatter and hungrier and that process repeats itself; 10, health departments don't often inspect fast food restaurants and supermarkets and so there might be poisonous foods at them; 11, employees at fast food restaurants and supermarkets don't always wash their hands after cleaning and so said employees might touch foods making said foods poisonous; 12, some foods, that're made by personnel that are paid low wages for fast food restaurants and supermarkets owners greed, and said personnel make that food fast without mindful and careful thinking, and so that food could perhaps have unhealthy errors;
If you/anyone is/are going to get fast food then you should make sure it is thoroughly cooked. Fresh salsa at any fast food restaurant is a good way to get Montezuma's revenge. From sea to shining sea.
