Sub station? DELI
Court bouncer TENNISBALL [I thought bailiff]
Stop and shop, e.g. RHYMES [I thought grocery or market]
Only the "creme de la creme" know DAMEMURIEL
SPARK; I'm shocked! And I never heard of RONEE Blakely. But I did know AUNTJEMIMA and CLETE Boyer, so it evens out.
It's a perfect touch having the last clue in the puzzle "solve" the theme.
