Let's be honest here, when was the last time a verbal apology from the waiter (as opposed to a manager or chef) has made up for a mistake/wrongdoing at a restaurant? Nowadays it's usually just a formality anyway. If you're dissatisfied with the service over something as trivial as that, then simply don't return to the restaurant. Is it really worth wasting a few bytes of FlyerTalk server space to complain about this?
