you know forgot about that lost little girl coming up and telling me her parents were missing - was going to take her to the nursing station it was closer than the city hall and she was crying. but out of thin air - security people surrounded us and make it plain that I was to leave her they would take care of her. only one looked like a security guard - the others were painters, cleaners, cm, and other folks who are always there - but sometimes you just don't see them.
feel bad about leaving the child since she trusted me - but got over whelmed.
We have played spot the security (we play odd games when we travel). We've watched security do a multi person tail and handoff with the nod like you seen done in movies - many times. They'll decide someone needs to be followed and they'll follow them.
Watch for "Dads without families" - chances are pretty good they aren't really waiting for their wives to get back from Dumbo with the kids. (We've seen "Moms without families" get the handoff too, but security tends to be a male dominated.)
