Why this sudden trend?almost 80% of the places now open very late(or early?!..),some 5 am some 6 am,some 7 days almost 24 hours.Chatting with the girls,they say late night clientele is not so classy and not many either: so why?too many parlour?need more open hours for profit?less clients?greed? I have noticed that the "classics"are not open all night...
