detailed. Never even crossed my mind for some reason, which is weird because I always tip at the basic carwash...I get the $10 wash and have them put an extra 5 on my card for a tip. But when I get a detail (which is anywhere from 150 to 300 depending on the level of detail I get) I never even thought to add a tip...

Maybe because a detail feels like more of a car maintenance/mechanic type of service? I mean no one is tipping when they are getting new brake pads installed, tires rotated, or an oil change. But since I always tip at the regular car wash now I feel like a jerk...
