4 oz is a pretty standard burger. A standard burger is about 1/4 lb or 4 oz. Many people use american cheese because of it's melting properties, it gets gooey and spreadable, while cheddar gets more crispy. Some people don't like cheese at all. All cheese slices are about 100 cal give or take. So, that burger is about 750 calories (I didn't include the lettuce, tomatoes, pickles, or mustard, because that's total about 50? so maybe 800 cal).  It's a big meal, but if you have a light breakfast and no lunch the burger and fries are within a regular caloric intake for a day. Fuck the milk shake. I wouldn't touch that with a 10 foot pole. We can eat good food, many of us could not finish the burger, but having some tasty things isn't bad. It is that she just makes garbage food all the time and eats like 6 burgers.
