Drinking coffee and eating gas-station sticky buns, a couple in their early 30's -- SPENCER (sly and smart, wearing a cheap plaid suit) and AMANDA (ADHD, wearing a pretty dress) -- sit across from each other at a table in a porn shop that’s on its last leg.

Good luck with your screenplay.

"in their early 30s"  is correct. The apostrophe turns it into a possessive of 30. I am surprised that a porn shop is providing coffee and buns.

This may be a difference between English as it's writen in the UK and America.  According to my reference from college (Simon & Schuster Handbook for Writers -- Second Edition), you should use an apostrophe to form plurals of letters ("Billie always has trouble printing W's"), numerals ("The address includes six 6's"), symbols (&'s) and words used as terms ("The for's in the paper were all misspelled as four's").  The one exception is with the plural form of years (1980's or 1980s), in which case either is considered acceptable.
