I recall asking about the chain and rear cassette when I brought it in, and was told today that they weren't that worn. They did get the seatpost to move though, for which I'm grateful; however, it's not truly free, as I wasn't able to move it and was told that I need to hit it with some PB Blaster and work at it.
I dunno, I guess I was expecting them to find a badly stretched chain and worn gears, and recommend their replacement, without me asking--they're supposed to know be able to find this on their own, aren't they?
