Local command run on server?

[Mr.Peanut]

One final MP question to add to my recent barrage.

What happens when commands that must be run on every client are instead run only on the server?

For example, Drop, Say, PlaySound, PlayMusic, Hint, SideChat, VehicleChat, are commands that must be run on each client to be seen/heard.  If these commands are run only on the server are their effects not seen/heard by anyone?

(if a tree falls in the forest...)

You've got it figured out just right.
If only one machine executes a local command the rest won't get the consequences of that command.

Thank dog for that...
