but sometimes they have a special for $0.99. How much do these $0.99 cheeseburgers cost? Why are they on sale - were they mistakes from the last time? Also, I need to know so I can figure something out if it is more worth it to get a medium coke or an extra large one and which is larger the regular fries or the upsized ones? And why do they sometimes have mint milkshakes at st patricks day? Could those guys also have cranberry sauce or stuffing milkshakes at thanksgiving? And is ther such thing as McDonalds pizza. Finally, I know that lots of McDonalds stop serving breakfast at around 11:00am, but can you get Big Macs and Double Cheeseburgers and other stuff before 11:00am? I just need to know all this stuff cause I have to figure something out. And if you ask for no salt on your fries, will they do that for you? Abd how often do they clean the bathrooms at McDonalds?
