I've worked with quite a few service advisors in my career that did that. Coincidentally, they are also the same ones that see dollar signs light up the room when a 70 year old pensioner drives in with their 1992 Escort that has a mere 20,000 km on it, and use scare tactics to sell them every service under the sun. How long they last all seems to ride on whether or not your SM has a conscience, or sees the same dollar signs.
And no, I don't use this avatar anywhere else. I don't have time to go anywhere else.
