Lancs Police have been doing this for months and it doesn't seem to have caused any problems yet...
Those two Romanians I got to know quite well thought it was quite nice of the Police to be so caring, even gave them coffee and biscuits when they turned up
Allegedly conversation went something on the lines of
"Hi girls are you prossies?"
"Of course we are! Why do you think we're in our knickers and bras? And why else would we be here?"
"Is there a bloke living here with you"
"No, don't be stupid, just us. You can come and see the bedrooms if you like...."
"Have you got enough food to eat"
"Sure, we're fine! Come and have some coffee and biscuits"
So they had the coffee, exchanged phone numbers and went on their way
Next time I saw the girls they said "the young policemen in this country are very nice to us..."
