How much do you take before calling a T?

[Almost Always Right]

Sanders - That is legitimate quandry that all of us go through(and some are still going through it).
1st things 1st - Read Rule 10 Sect 5 - The Coaches Rule
That will give you a foundation.
Some little things to remember:

If bench personnel is distracting you or your partner, they are out of control and need to be acknowledged.

If it is personal.

Know the buzzwords in 10.5 - Disrespectful / Unsporting / Unsportsmanlike / Inciting / Attempting to influence. . .etc. These can make the communication regarding these situations short and simple.

There are many other aspects in which I am sure people on here will respond with but this should give you a little bit of assistance in your plight to set your boundaries.

Good Luck
