I am not really good at drinking and I normally have only a glass of champagne or two when I dine out. Next month, however, I plan to take a special bottle of wine costing about $650, to a favorite high end restaurant of mine. (I will dine alone, so I will probably have to share it a lot with the staff since I can not drink that much alone... LOL)
The restaurant will charge corkage fee, and I fully underdstand I should pay normal gratuity of over 20% to 30% on the final bill of food and corkage fee. My question is, how much gratuity am I supposed to pay on the $650 BYOB wine? Should I pay 20% tip on $650 as well, on top of the 20-30% tip on food and corkage fee?
