We had an all inclusive week, but tipping was still optional for all meals. Our first morning we went to La Nao for Sunday brunch. I wanted to be kind and tip our server 50 pesos on the tablet he presented to me, but the waiter tricked me into tipping 50 USD as he changed the currency quickly before I wrote in 50. An hour later I checked the resort app and noticed I was charged $50. We immediately went to the restaurant, spoke with the restaurant manager AND server who admitted he was surprised I tipped that much. The manager said that she would reverse the charge, and when I still offered to tip the 50 pesos, she refused to accept it due to the inconvenience and initial dishonesty. The charges were not reversed for 48hrs on our account, so we then went to the front desk and they had us sign some papers and assured us they would reverse the charges. When we checked out, they presented the final bill WITHOUT the $50 charge, confirmed verbally that it was removed. Then when we got home, I checked my credit card statement and they added the $50 again! I called and spoke w/the mgr and he said that I had signed the bill and agreed to pay and refused to reverse the charge. This place has super dishonest waiters and managers and billing. DO NOT TIP unless in cash. I can't believe how dishonest these people are. Also rooms are a little run down, AC did not work well, towels were old and pools often did not have any clean towels. Sky pool often closed for events. AVOID THIS PlACE!
