crowd control

Have you watched the grand celebration of Pinoy Big Brother earlier this evening? Actually, I didn't know that it was the last day of the said show until I saw somebody on facebook announced it, so there, was able to catch half of it, at least. Anyways, have you notice how particular they are now with their crowd control management? It somehow amazed me to see that they have enough barricades to cover the area. Though I'm not sure if they have this velvet rope laid on the entrance of the celebrities outside the venue, but I think they have.
You see, I believe that every event coordinator must make sure the safety of everyone that will attend the shows, probably it is now one of the many precaution and requirement whenever an affair will take place in certain place, stanchions is for sure one of the best example of an elegant and simple crowd management thing, something we often see in queing for lines and all.
