I had a terrible case of a client spending $6000 per month on a visibly innocent things and refused to move it into dedicated because he could not believe it can bring any savings because "clouds are cheap". Until i just did it at my own expense because with my retainer, a server cost me something like 1.5-2 hours of work per month equivalent.

By the way, it's only in the US. In Europe, people are a lot less zombified and susceptible to advertisement/brand image.
