I had to rush home to post this - DF and I were eating at a restaurant this weekend, and a small child was going around all the diners asking for money. The wait staff asked the parents twice
to control their child. They took him back to the table, then let him loose again, no stern words exchanged.
He finally came over to us, DF opens his wallet, takes out a prophylactic and hands it to the child. Child runs over to parents to ask what it is. Parents keep tighter reign on child afterwards.
