When they say that it shouldn't be on your players card account. You will have to sign and that will go to your Tax Account.
I say something like, yes I was playing on my card. Not sure why it didn't catch. I have have problems in the past with your system.
The Casino is a lot hipper to pulling the card. Most places don't like it and it can cause you some troubles.
An individual has to make their own choices if it is worth it or not and be ready to talk your way out of problems.
At times you may have to talk to "higher ups" if you start abusing shots too much.
This is all give and take and requires time for experience.
Usually it is best not to get upset or cause any type of a scene.
Some players get loud and abusive but I don't find that strategy works very well.
