The clue is in the name!
cubiertos from the verb "cubrir" - to cover, to cover up, to obscure, to hide
I feel the charge is fully justified when there is e.g entertainment maybe piano etc. So no complaints there.
Cover charges operate not just in Argentina or Italy. In the UK they exist and in many of the best restaurants (I'm not saying I am a regular patron!!
But my attitude is they have to be up front and mentioned in the menu including where this is posted outside the restaurant. Again no complaints there because there is no attempt to obscure.
I have a totally anglo-saxon attitude to tipping whereever I am and that includes taxis and just about any other situation. It is a bonus for good or at least acceptable service and that is to reflect the service from the establishment overall not just about whoever happens to come to the table. so if the toilets are unacceptable that gets mentioned and no or only a derisory tip. 10% more or less is my usual.
Some restaurants pool tips anyway. There was a big issue over this in the UK because 1. tax payable and 2. restaurants did not make it clear what is their policy - now most do explain whether the tip goes to the person waiting at table or is pooled either with the restaurant staff or simply goes to the organisation as a whole to be handed out as bonus.
If I find the cubierto is a nasty surprise at the end of an unpleasant dining experience then no tip and if i'm properly hacked off then its time to call the "manager" and let rip
- and the "conversation" can be as loud as becomes necessary to make the point
- depending on who im with of course! :wub:
