Ickky TO sit. ends in Technical

[ace]

Oh boy, My last game of the weekend. I've dealt with stupid coaches all day. Screaming for every single little bit of touch. So yeah it was eventful. 8-9 yr old boys game.
A1 OOB inbounds pass full court press - counts get to 3 A coach calls timeout partner acknowleges. Table didnt hear it I had to relay. Clock stopped at 1.4. Partner and I huddle during timeout discuss. We decide to put 5 seconds on the clock. Partner says he acknowleged at 5 seconds to go. Parter tells A coach. I tell B coach. B coach starts getting IRATE! Tells me I cant add 5 seocns blah blah blah blah blah....(I had a davism :-D heheh) Coach tells me"YOU DONT KNOW HOW TO CALL THE GAME!" I looked at him with a straight face and calm voice and said "they call me every week dont they?" he turns around. 1st horn blows hes still ranting. Partner comes over to me. A calls successive timeout. B still yacking. I've given him 30 seconds (30 ft of rope)to hang himself 20 ft(sec) too long. WHACK! He walks back ot his huddle. Green shoots. Impound the ball last second shot ball game. Sign the books he wants to talk some more. Tell him games over. Put on my jacket and walked right out. I prolly opended myself up for some backtalk Im young and have a spit fire respsone sometimes. most of comments were trying to diffuse the situation. My partner said he was glad I whacked him because he was about to do it. I feel like I handled the situation very well considering my inexperince with coaches.
I'm still waiting on my NFHS rule books (been 2 weeks - called yesterday said itd be here today or next week) so I cant check a book about adding seconds. The timekeeper had too much delay in stopping the clock after the acknowlegement to be fair. Advice, rules, and constructive critism please.
