Agreed Im a Hyundai/Mitsubishi tech and have been a tech far too long, but I can say without a doubt. A clean car, some cookies, or a personal thank you gos a long way. Some of my customers that only deal with me will do things like this. So when they spend good deal on money taking care of their car, I hand wash it myself! It goes to show if youre nice and easy going, your tech will go the extra mile for you!
