I was just in McDs with DD and DP having food and a man came to give out balloons. DD received one as well as three other children sat opposite us.
About 20 mins later a couple of young lads come in about 10yo. One runs around the tables, jumps grabs one of the other families balloons and runs off.
I was 
at the cheek. I told DP and he said it was none of my business and as I wasn't 100% sure whose the balloon was. But I knew it wasn't the boy's who took it.
Anyway just as we were leaving, one of the children from the family was looking for a balloon, it must of been his that the boy took. 
Would you of said anything or was I right to mind my own? If DP hadn't of said anything, I would have confronted the boy or told his father.
