TO request when you have no timeouts

[Knights_Coach]

I always thought refs granted the TO, then a tech ie Chris Webber Michigan. Growing up we were always taught, "don't call a TO if you are out, the ref 'will' give you a tech." It was never, he "might" give you a tech. I've been searching for this answer. Here goes the scenario:

During our overtime game. With seconds left in the game, it's tied 52-52, both teams were in the double bonus, the ball is dead, Team A(them) had the possession on the baseline trying to inbound ball & advance down the court. Team B(us) played full court press and almost got a 5 sec count, team A's inbounding player signaled timeout to the referee near him, who was right next to him. He never granted it, shook his head no. Team A inbounded it and it was tipped by Team B toward the half court line, Team A's possession there. I tried to ask the referee why didn't he get a tech because it was clear that he was requesting one. He then told me, he doesn't have to grant him one. All the while Team A drives to the hole and and gets fouled with 0.3 seconds left. Sinks 1, Team A commits a lane violation on the second. We didn't have any timeouts and w/ only 0.3 seconds we rolled the ball but didn't make the shot, end of ball game 52-53. We were the #8 seeded team vs the #1 seeded team.

NFHS 2014-15 Rule 5: Scoring and Timing Regulations, Section 11: Charged Time-Outs, Article 6 says: Time-outs in excess of the allotted number may be requested and shall be granted during regulation playing time or any extra period at the expense of a technical foul for each, as in 10-1-7.
PENALTY: (Section 1) Two free throws plus ball for division-line throw-in. (Art. 7) Penalized when discovered.

The Bible says thou "shall" not kill, adultery, steal, etc. Shall means "will" not "sometimes" or "at discretion."
