Yes, I know how FIFO works :)

I didn't pick up that it was under warranty - that may be the big
difference. The place I use, I have always come in with very specific
jobs that I didn't want to do myself to avoid breaking something that I
couldn't afford to replace ("please remove the massive CPU cooler and
install these DIMMs") and have always paid by the hour. That may
get higher priority than a warranty claim, as I don't expect there's any
guarantee on getting warranty maintenance done quickly...
