Not something that we've really been troubled with at our own b & b, but it happened this weekend.
Not only did they manage to break a shower fitment and not bother to say anything but they walked away with a new toilet roll plus a full packet of sanitary towel scented disposal bags!
Not a huge value in monetary terms but theft just the same and earns them and the rest of their party a place on the black list. They won't be crossing the threshold again.
I'm told these bags are excellent for dog poo as well (but not too good for sandwiches!).
