Went to a regatta on Sunday and subway had a man dressed as a sandwich (I think it was meant to be?) who was giving out balloons to children. No problem with giving balloons to them but he gave both Ds (2.9) and dn (17 months) a balloon that hadn't been blown up.
These where both grabbed off them as soon as they were given them but I can't help but think its a rather daft thing to do in the first place?
