It depends on the part of the country where you live.
In London, we had conductors on the old Routemaster buses, and the for a while on their replacements - but I haven't seen a conductor on any of our buses now for about a decade.
The answer to this problem (with the girls wearing the hijab, is to let them on, and the moment anyone starts on them, stop the bus and get the bullies ejected.
This would be an inconvenience to begin with, but once the bigots went through this a couple of times, they would soon learn to shut their odious gobs.
Seriously - how weird is this story?
Imagine you're on a bus, reading a paper, and a girl gets on wearing a hajib. You would have to put your paper away, get up, walk over to her and abuse her!
That simply doesn't make any sense.
AOG - the line you've taken is really quite shameful. I only hope you're taking this ridiculous line in order to provoke a debate.
