Unless you are very, very young (I'm talking abt below 20yrs), you might remember 'The Centrepoint Kid' era where socially deviant children would hang around Centrepoint in their outrageous fashion, etc.
There was one time where there was a blanket ban where anyone, as long as they are in school uniform, are not allowed into arcade and pool centres at all times of the day.
During the era between late 80s to end 90s, schools were facing problems of kids playing hooky & juvenile delinquency and apparently there was some sort of 'unofficial arrangement' of sorts between arcade/pool operators and schools I think. Those who are older might remember the wave of complaint letters and how principals would usually make very serious announcements on catching some very famous Primary 7E or Primary 8M student smoking at an arcade whilst playing hooky, etc.
