I've had something closely resembling RIS from La Rochelle or Bordeaux before, no doubt informally.
I also once had instructions to keep well away from the Le Blayais TRA; I was impressed because normally the French ATC are more than happy to give you a squawk, and watch you on radar as you infringe one of their TRAs, all the while they are talking to you, asking you for departure, destination, confirmation of level. Then 5 months later you get a letter from the CAA .
