"Tell me more about how this would work in your games. First, the RAW does not seem to support this, beyond the DM determining how NPCs and creatures react to someone who is raging. In your example, would you, as the DM, decide that the player attacks the table? That's not really my style. I want the player to play their character and they decide how their character acts. Also, intimiation is a CHA check, so it would be waste to burn a rage to intimidate as it gives no mechanical advantage. "
That is depending on the roleplaying of the player. The whole situation is a bit constructed and hypothetic but let us say it goes like this:
Conan the thirsty roleplays his character being in absolute need for a drink.
DM : The waiter seems to ignore you
Player : I get really upset and clench my fist
DM ruling you: get enraged and you want to hit something
Player either playing along or DM ruling: Make a wis save to see if you control your rage if it fails you hit the table.
See, this is just a funny RP situation to eventually bring the players into trouble or some other hook. Since it is no actual combat situation and besides a table no one gets harmed it is ok to burn one of the barbarians resources, since he probably gets it back. If for some reason I as the DM decided a tough fight ensures somehow shortly after that, and the barb would be treated unfairly because he is missing one of his resources I would DM rule:
The city guard arrives weapon drawn and out to kill, you will not leave without getting your drink, you grab a mug and down it, and it resets your daily uses of rage.
