Gifted bill and dessert for dinner

I spoilt my parents for their 43rd wedding anniversary with dinner at Fahrenheit in edenvale. The outstanding meal and service was finished off with compliments from the kitchen a beautifully decorated cheese cake. Congratulating the couple. When the bill arrived certain parts of the bill had been deducted as a gift to my folks. This is what I call amazing service. I recommend Fahrenheit to anyone. Brilliant on you Fahrenheit
