A: This question is one that does not always have an easy answer. A tip is a personal expression of one’s gratitude toward another person who has performed a great service which is worthy of aforementioned monetary gift.

The tip should be equally proportioned to the level of service or the level of expertise the service was performed in. The standard percentage for a job well done is 20% and can increase from there based on the client’s expectations and how well the driver met them. If the service recieved is sub-par then rightly so the gratuity should reflect that lack of initiative.
