So you took the frame to them on Tuesday, and they are building it up for you in time for a race this Saturday? That's incredibly quick service for someone who didn't buy the frame from them.
I'd rather pay the price and NOT have things thrown together on the fly. Aren't you just a bit concerned about the integrity of the build, considering the limited amount of time you'll have to get a feel for it before racing? Knowing you needed the frame for a race Saturday, wouldn't it have been better to get moving on this a little sooner?
Maybe the bike shop has a little bit of a reason for an attitude. . .
