Times Quick Cryptic 2315 by Joker

Hello everybody.  I enjoyed this puzzle, which felt trickier than my time would suggest.
My last in was 11d.  12a made me smile to solve, but not to write up in the blog!  I liked 3d because it could be very apt for anyone not a fan of the relevant wordplay.  It would also indeed be irksome if the setter tended to leave bits out of the clues.  Happily, all present and correct here – thanks Joker.
