breakfast was poor they try to charge me for dash of milk I requested

the day we leave they said to us we need to pay s/ 50.00 for litter damage on the table so I said to the staff to should me it was little burned on the table I really realise but my girlfriend ,she saw that when we arrive it was already done so I told them no try to be smart with us ,so the staff call her manager and she said it is ok.
