When I worked at a shop people would ask for me and this guy Keith specifically. To the point they wouldn't even let someone else do a simple oil change. When asked why they did that 90% of them said because "everyone else is retarded. I know I'll get what I'm looknig for from either of you the first time." Of course that isn't word for word what they said, but it was more than implied (some actually did say that).
One person claims to think the same exact thing I did, so I said enough.
