A light press fit, if they made it correctly. At the LBS, we have some bearings that are a skosh oversized for the frames that have a sloppy fit with the normal bearings. Pro tip for anyone planning to install one: put it in the freezer to shrink it, and warm the frame to expand it, before you attempt the pressing. The bearing is oversized because there's a super-thin shim on the outside, and it can crumple quite easily. Oh, and it's not BB30.

On the original topic, what would irk me is having my bike be offline while getting this taken care of. If you're missing training, racing, or important rides, it's not strictly no-harm no-foul anymore. Also, the customer is supposed to pick up the tab on labor, which would come to about $150 where I work.
