Again here we find the "it depends" factor.
Whether or not you receive satisfaction, takes the correct and proper action and pays you will depend on the following:
Is this a large casino or a neighborhood one?
How well known are you there? (How familiar is your face?)
How high is your Player's Card ranking?
How much competition is there for your gaming dollar in the geographical area?
What is the prevailing attitude of management toward keeping the player happy and thus returning?
And, sometimes most important:
What is the attitude of management toward VP Players in particular?
When this has happended to me, I have sometimes had to go one or two steps above the slot manager, but if you have a good reputation in the casino and this has not happened too many times in the recent past, you will usually be paid.
Another thing you can do is to bring your host in to the situation to speak on your behalf. This has worked for me.
I have also developed the habit of inserting a definite "pause" in to my usually quick play if an Ace(s) comes up so I am sure to verify that I have held the card(s) and that my hold is still on screen before I hit the draw button.
