Bloody Hell! I suppose if she's paid for the party & the bears, she technically "owns" them, but the point of those parties is that attendees get their own bear. What a cruel thing to do to children, and after they personalised the bears, too!
Reminds me of the recent thread on here where the OP wanted to take her Dds friend to BAB for her Dds birthday treat... but only Dd was to get a bear. She was quite rightly told to treat them the same or forget it.
