I'm a student from Belgium and I often go out during the week but find there are no late-night buses.

I can't afford to take a taxi each night so I have to catch the last bus at 11.30pm - so no discos for me.

And, of course, when I take a late bus at the weekend, I'm surrounded by drunks.

Is it possible to employ security guards on late-night buses?
