Or just ask for a cup for water and fill it up with soda
I don't understand people who don't go to McDonald's.
I don't even understand you people. A small is like 18oz. Why would you ever need more soda a sitting than that?
How bout this tip:A Double Cheeseburger and a Mc.Double are the same burger. The only difference is one extra slice of cheese and 1$. You pay an extra dollar for one more slice of cheese on the Double Cheeseburger.
I bet nobody has come up with that.
