Sad to hear about your losses, the decent venues have looked after their customers during this difficult period, some have not!!! The properly registered venues (for French tax purposes) and I would think Bills Lakes fall within that category have received Government support (similar to the UK system) so there is very little if no excue to treat customers better. As a former fishery operator in France (retired now), my best suggestion would be to report your story to the wide carping world, forums, magazines etc., it probably won't get your money back but at the very least it will put people off going to money grabbing venues who simply don't care about their customers! Good luck!
