What happens to my front money if I get pulled up?

Scenario:

I have both credit and front money deposited at my casino's cage. If I were to be identified as a counter and had a note placed on my player card file, what should I be ready for when I go to the cage to withdraw my front money?

What is the experience of other AP's playing on credit and front money?

So far I have never had problems with my credit and front money accounts but I have never been pulled up in a casino that I had credit with.
