Midnight is when the vampires come out, so everyone has to be at home at this time. At least this is what my grandmother told me - just to scare me, of course. Anyway, local authorities here think the same:
Vientiane authorities are warning entertainment venues to strictly follow the regulations, in particular the midnight closing time, to maintain social order. The proclamation is one of many efforts the government is making in preparation for the 7th Asia-Europe Parliamentary Partnership Meeting and the 9th Asia-Europe Meeting Summit to be held in the capital in October and November respectively.
I am very sure that all participants of the summits will never ever be out later then midnight. Oh, wait, some venues, not mentioned in the article, have a special permit to open late. Guess for whom?
