My museum has re-introduced bag checking on every visitor who walks thru the front door. This is due to the terrorist threats etc. Paranoia slightly, but still. I was on the bag check table today, and a small girl came up to me holding products from the shop. I told her she had to talk to her mum about buying things, as she had the money and I didn't have any. She kept at me (as much as a 4 year old can). I told her again to talk to her mum and ask her if she would buy them for her.

"But mum will say no"

So her solution? Ask a stranger to buy them for you!
