I'm Lovin' It

Going for a drive with a friend you've had for quite a while, Alfred Jones, he soon begins to beg for McDonald's. You explain that there's food at home, but he insists on telling you a secret, so long as you get him the McDonald's he wants. You pull up and walk in, anticipating his secret. What is your long time friend's secret?

I do not own anything save for the story itself.
Hetalia and its characters belong to Hidekazu Himaruya and McDonald's belongs(?) to Steve Easterbrook.
I really could give two shits less who Sprite belongs to tbh.
