Indeed, but my whole point here was that his material wealth is immaterial in this instance, so "few bob" stands in perfectly well for I don't know how many millions. It's exactly what I'm driving at.
You're too modest!
A few bob, to me, is suggestive of the local builder who got a couple of properties turned around just at the time that the market was booming. The carpet salesman who managed to contract 80% of the new offices in that new building by the roundabout one month, and so got a nice bit of commision in that pay packet, thanks very much. That fellow who orders rice for everyone rather than sharing a pilau between two (we'll never eat it all, but who cares!)
To use such a phrase to describe a man worth an estimated $5.2 billion (according to Forbes) is top quality understatement. Whilst I acknowledge your commendable modesty in refusing to admit that, know that I hold this particular piece of understatement in the very highest regard, and can only apologise for the evident embarrassment I have caused you in expressing my admiration for it.
