I just made a reservation in French over the phone for a hotel. I am so relieved I made it through without TOO much difficulty, although I had to ask the man to repeat his questions a few times. I haven't really needed to speak French in years and years and years. Even when in France and Quebec, since in both places I've only traveled with English-speakers, and ordering from menus doesn't usually require much of a conversation.
I like to think that at least I enunciate my numbers much more clearly than would a native speaker.
