@JO... my "lousy" experiences were only in part because of the language barrier. I did say "good day" in French, just to be nice, but that's about all I know (ok, about 4-5 other words perhaps). But it gets frustrating to give FIS an initial call on the proper frequency and not get a reply! Nothing! and it wasn't just once, it was a number of times. And then at one field, we almost got hit by a jet trainer because of the poor accent of the guy in the tower and the jet pilot "showing off" (overtaking us while we were on short final and scaring the living daylights out of us ... we didn't know his intentions). Long story which I won't go into now.....
