I had a discussion with a Bali frequent visitor who told me if 21% was added to the bill they did not give a tip, because service charge was included! As I always and I mean ALWAYS tip, I could not understand this. Please give me your opinion! If I'm in a Warung I would always tip according to their prices. If i'm in a "Ku de Ta" or "Sarong" I would tip according to their prices. I'm a wrong doing this????Really appreciate your opinion! Greetings from Holland!
