Depending on the quality of the BB they installed, I'd guess the labor cost more and the shop won't recover that cost. I'd also doubt that the manufacturer would cover the BB after you rode with it loose (doesn't count as a manufacturing defect). So you should give those shop guys a big hug for doing this free under their own warranty. The old one could have been too damaged to work properly, or was at least damaged enough that it would never operate smoothly again.
