A pet peeve of mine. The opponents' CALL
a timeout. As the official is reporting it to the table, I'm huddling with my assistants while my team is grabbing water bottles. Now I'm done huddling and I don't know if it's a full or a 30.
The calling official should take a step or two towards the non-calling bench, and say in their general direction (or pop his head in our coaches' huddle if we are nearby) and say "Full, coach" or "30, coach". Just as a courtesy.
