There's this programme on the telly - don't know whether you've seen it - where they send a millionaire undercover into an impoverished local community. He spends some time there and then shells out much-needed cash to those he judges worthy recipients.
I think the programme could work the same way in reverse. They could send me undercover to pose as a millionaire at a place like the Savoy. In order to be credible, I'd need to be holding some serious folding. It would be a useful insight into social relationships and the state of the British class system.
