When we went to Manila last October I passed by a store ( I forgot the name) and it was crowded. I don't know why but there are a lot of people waiting outside. The manager is entertaining those people and commanding his staff to organize those people. I think I heard him say "get those stanchions here!". I think before you hold a promo or anything that will drive people to go to your store, plan first and see how people will react to the promo. It is better to have a clean and organized one than to have a bad reputation of having a bad service right?
