T or Yellow Card

[ref18]

My $0.02:

If you think the penalty is too harsh or will give the other team an unfair advantage, then behave. We don't just whack coaches because we feel like it, they have to earn it. If they don't do anything to earn it then they won't get disadvantaged by the technical foul.

There is nothing wrong with the rule, everyone knows about it going into the game, so they can't exactly say it's unexpected and out of the blue.

Don't complain, suck it up and behave.
