Can a prostitute utter these words and be taken seriously?

Who's that girl there?
I wonder what went wrong
So that she had to roam the streets
She dunt do major credit cards
I doubt she does receipts
It's all not quite legitimate

And what a scummy man
Just give him half a chance
I bet he'll rob you if he can
Can see it in his eyes,
Yeah, that he's got a driving ban
Amongst some other offences

And I've seen him with girls of the night
And he told Roxanne to put on her red light
They're all infected but he'll be alright
Cause he's a scumbag, don't you know
I said he's a scumbag, don't you know!
