Amused at a news article I saw today:
Everything I said in my second post is true. Children are allowed to gambol in "coin palaces" in England, and are encouraged in most by the addition of small toys as extra prizes, on top of the money. However I read in the paper that a bookie (off track betting organisation) was recently prosecuted because an advert of their's for gambolling on football included a photo of a 23 year old professional footballer, and you are not allowed to show people under 24 in gambolling adverts in case it encourages children to gambol!
