Tipping at the Car Wash

[jamesglewisf]

Question via email - I am having the inside and outside of my automobile fully detailed,, including trunk and engine. It is a day long process.

How much should I tip?

Answer - 10-20%

By the way, don't have your engine detailed. That's one of the things auto mechanics love the most because your next trip will be to them.
