personally I don't take anything but my boyfriend will pretty much take anything that he can get his hands on that isn't nailed down!! He'll take glasses from pubs if he likes em, he took an ashtray from a restaurant once, he'll take all the bathroom stuff from hotels, plus any left over condiment sachets in restaurants etc!! I can't take him anywhere! The worst is when he takes stuff and doesn't have anywhere to stash it - I end up having to put it all in my handbag so I look like the thief!!
