They call me when my repairs are done. They also call me when they recieve parts that they ordered and know that I'm interested in, regardless of whether or not I actually end up buying them. Hell, they even gave me their extra pizza the last time that I was in there.
On the other hand, the fact that I've been shopping there for nearly a decade now, am good friends with half the staff, and offered the oner's brother-in-law a room to rent probably put me on their good side.
