A local shopping mall had a problem with the local lads hanging around one particular entrance. It became so bad that the locals would avoid going anywhere near there - last time I passed I could hear classical music coming from the speakers near that staircase and I saw no sign of any young males at all.
Mind you, the said shopping mall had expanded a few years ago - added new shops all aimed at young people with money to spend - put in a McDonalds where there was none before - and this staircase entry led straight to this area!
