You must apologize in advance to your personal (same one every time) service advisor/writer-upper, and advise them the you are an ****, microscopic, nearsighted car owner while you slip them a $20 every time you come in to DROP THE CAR OFF for something new. (Not on a come-back if it ever should be necessary). They will then learn to deal with your picky-a$$ self & will always route your car to the best, most carefully trained technician for the job you have ordered.
I have done this for years, and always apologize for the freak that I am, and tell them I couldn't deal with a customer like me, but to please understand. I have always been satisfied with the work performed, and the personal attention I get. I just can't help what I am when it concerns my personal car.
