Tracy’s story: “What do they get out of it?”

I got off the bus at Templars Square, hadn’t walked two paces when a car full of lads drove by, shouting ‘Hey love, you working!?’ I ignored them as it’s the best policy, but it’s threatening to be shouted at by a car full of men late at night (it was 10 pm and there were not many people about).
What do they get out of it?
