La Ganania - Mogán

We are reasonably regular patrons of this restaurant 6+ times per annum. We were 6 people for Sunday lunch and had two large and 3 small beers before two bottles of wine. When the bill arrived the Large and Small beers were reversed and €1 added to each bottle of wine. We noted the sharp practice but overlooked it as we had guests with us. We returned 5 days later for Lunch for two. We had the same wine a Rioca Reserve and when bill was presented the wine was 50% dearer than 5 days earlier. When proprietor was questioned she insisted it was correct and we paid the bill without further question as we had done previously. On leaving we asked to look at the wine list, which confirmed our doubts we were charged for a Gran Reserve rather than Reserve a 43% overcharge.We were refunded the overcharge with apology. Recommendation CHECK THE BILL One overcharge overlooked as minor mistake (while we had doubts) but second overcharge within 5 days Error more like embedded sharp practice.
