It's no surprise to me at all. The best bit is most charity shops wouldn't begrudge someone a couple of coppers off of something. I've often been given a bit off when I've been heard to tell whoever I was with "I've only got xxx spare". I don't say it loud enough to get it happen deliberately, but when I've been heard to say it have been told it can be reduced a little if it would help. To steal from a charity shop is taking the biscuit isn't it?
