How can I tell conditions and rules?

I'm relatively new to playing BJ in casinos(only twice). I was
wondering the easiest way to tell the rules that the casino uses at a
particular table???

I remember that on the table is marked what the dealer will stand
on(ex: Dealer stands on soft 17's). But I don't know how to tell
rules like: double after splitting, late surrender, and all of that
good stuff??

Thanks in advance
