Yes, actually you should. Send a tell since that beeps and comes thru regardless of which chat tab someone happens to be on.

I understand completely since I mostly avoid PUGs myself for much the same reasons as you. That said, most PUGs aren't too bad. Based on my limited experience, they generally aren't organized well enough for anyone's errors to really stand out. That's a little different in raids, where you generally see more experienced (and more demanding) players, but you should be OK on the quests you're running.
