And there are lots of others.
For example, take a look at their respective breakfast habits. While in France the most important meal of the day could be a pastry or perhaps even just a cigarette and coffee, Americans like to start the day with a big plate of eggs, pancakes, sausage and bacon.
On top of that, when they take their coffee break, the French sit down in a cafe with a friend or a book and while away an hour or more, while in the US a coffee is something to be consumed on the move.
And these differences stretch beyond how people eat and drink.
While dinner tends to be at around 6pm-7pm in America, in France it's unlikely to be any earlier than 8pm.
A US diner is likely to find themselves extremely hungry in France come early evening when instead of sitting down to dinner the French are pouring their first apero of the evening.
