Bouncing the Ball Hard - a Tech?

[Cornellref]

JV Boys last night. B1 fouls right near the table and my partner calls him for it and turns to report. Then B1 takes the ball and spikes it to the court pretty violently. Given that this all occurred right near the table area in front of the whole crowd, I felt he was not just taking out frustration but showing up my partner. I whack him and get no complaints from any coaches or fans. Anyway, I was wondering if there is some limit you experienced guys use when players spike balls on the court after a call goes against them. Could a warning be given instead?
