casino wont do anything, they cant take the money of you and for £300 the most they will do is bar you. They may decide to add this to a national bar of all stanleys , they then would inform Grosvenors, lci and gala because they all share the same network for following cheats. I would just say you aint got the money, more than likely its the same manager that gave you the ticket and hes trying to cover his arse as he fucked up.
