How do table game comps work in AC?

[NickMPK]

I've never played any blackjack in Atlantic City, but I am considering trying it out next time I go.

How do you get comps at these games in AC casinos (let's say Borgata)? Do they accumulate automatically on your player's card? Do you have to "check in" and "check out"? Or is this just a judgment call where they might give you free food or room or whatever?

Also, what sort of comp can I expect from playing blackjack at $25 or $50/hand in terms of $/hour?

Finally, will they revoke comps if they think you are counting cards (I'm not going to put any serious effort into this, but I might raise my bet if the count seems obviously high)? Thanks for any responses...
