I've left all my money to charity. 5 named charities, money, mainly the value of my house, split equally. This is because I have no dependants and otherwise the government would get the money, or so I believe.
BUT while I was planning this I read that Cancer Rersearch shops had leaflets about making wills so I thought that would be useful, and went to my local CR shop. The 2 members of staff had never heard of it, insisted there couldn't possibly be such a thing, and started laughing as if I'd made some sort of joke. This was about 10 years ago, I've never been in that shop since, either to donate goods or to buy. And needless to say, CR was NOT included in my will, so missed out on an approx £100k legacy (house current value about £500k). Please train your charity shop staff to treat customers with respect. My neighbour said she'd had rudeness in that shop too, and won't go in again.
