Two girls talking....
"Fred's gone and left me in the proverbial - lots of debts, no real future, no qualifications, maybe homeless soon if I can't find the rent..."
"Desperate times for you, then. I don't like admitting this, but when I was in a similar position some years ago, I did a bit of prostitution to make ends meet!"
"What?! I don't believe you!"
"Its true! Not proud of it, but it solved my problem!"
She went on to explain the ropes : how to stay safe, don't stay in the car too long, watch out for any boys in blue, etc.
A week went by, and the girls met again.
"How'd you get on?"
"Not bad. Had a bit of a weirdo last night, but followed your advice, and got rid of him very quickly! And the money is certainly going to help...."
"Good to hear it! Out of interest, how much did you make last night?"
"Seven pounds 10p"
"10p?!! Who gave you the 10p?!"
"They all did...."
