Cards aplenty

[SCalScoreKeeper]

Last two weeks I've given two yellows and my partner has given two yellows in varsity matches.

Gave a yellow tonight that I'd like some input on-between sets as teams are changing sides but within earshot of me visiting coach comments about a net call I made as the R2 "that's BS" to one of her assistants. I verbally warn the coach for language and as I'm finishing the verbal "F word" comes out of her mouth.I stepped out and asked for a yellow,explaining to my partner profanity was the reason for the card.

Mind you this all happened within about a 20 second window.
Does the time frame make this a red for everyone?
Should I have skipped the verbal and gone straight to yellow or red or DQ?

I try to give the coaches a chance to be model citizens and clean up but 2 profane comments within about 20 seconds crosses the line.Last coach I verbally warned for profanity cleaned it up and never was a problem for the remainder of the afternoon.
