I work alongside people who've claimed benefits at one time or another, and if someone's in receipt of a basic hand-out, there's no way on earth that they could afford to live the high life. However, that doesn't mean that they're illegally obtaining money. They could have a little nest egg somewhere, or be being helped out by relatives/friends. I think what you've done's right in principle, MWB, but if I was in that person's shoes, and hadn't done anything wrong, then I'd feel very angry towards you for putting your nose into my business. If you're proved right, then fair dues, but you could spend a lifetime snooping on other people if you wanted to. As one gets caught out, another one springs up.
