We tend to take consulting firms' claims that they're dropping low-value clients in favour of a small number of big, high-profile, accounts with a pinch of salt. It's not that we don't believe them, it's just that we suspect it's never quite as binary as they make it sound, and is often being used as a way of telling us that their business is doing very well, without resorting to the usual weapons-grade metaphors. Like "booming", or "exploding".
