Like the sibling comment here, I've seen this plenty of times too. Not on "most projects" or "most places", but certainly on most spectacular failures I've witnessed.
I don't think the one who's seen "hundreds" of examples could have done so without being an "Agile coach" or something, maybe a temporary contractor at most, either way getting a pretty arms-length look at how a team is operating or is starting to adopt a new procedure.
