This might come as quite a surprise to many Americans, but the vast majority of countries do not like to have their food and drinks to go - especially coffee. In countries like Italy, it can even be considered slightly offensive and absurd to take a coffee to go. What is the rush? Don't you want to enjoy it? If you ask for something to go, it is a pretty big giveaway that you are an American.
Coffee to go is pretty much one of the biggest backbones of American culture. It is crazy to think that other countries find this concept unacceptable.
