There are lots and lots of things that can/do happen
in rec ball that are different & usually tolerated, but in any case, you've got to learn to roll with it.

Such as
using "identifiers" when players don't have numbers.
allowing subs to enter without really being beckoned
due to a running clock.
dealing with scorekeepers who don't pay attention.
keeping track of A/P or team fouls on your own.
dealing with business owners not used to taking orders
dealing with players who's skill level has deteriorated
special rules for foul outs and defenses
players arriving late (not in book)
hanging on rim and slapping the board
slightly moving out of the designated spot
spirited smack talking amongst friendly rivals

Common sense must be used (as opposed to strictly going
by the book) when dealing with rec league players.
They pay to play.

If you're worried about losing your sharpness of signalling,
concentrate and do the same as you would if working "organized" ball.
