I think that’s a possibility, but I don’t think it’s a guarantee.

In terms of risk I think you’re right, no one is going to actively risk their job. However just working with someone you’re going to pick up a few things. It can start as simple as some internal application being set up weirdly.

To find the real long term problems and fixes, that will take time. Time to build that trust.

I also agree that if everyone is just going to the same Home Depot that’s going to bias things heavily and probably result in poorer feedback.
