Although French fries are arguably one of the most delicious foods to have ever been created, there is a time and a place that they are appropriate to have with a meal. Many Americans may be under the impression that they are always fitting, even though that is not really the case. While it may be common to order them on the side of a salad or pizza, in other countries, it is considered strange.
If you're an American traveling abroad and you try to order French fries with your pizza, there is a good chance you'll end up with French fries on top of your pizza instead of on the side.
