A paragraph from the book I mentioned earlier. (backstory: P38 pilot, D.K. Willis is evading capture by the germans after being shot down over occupied Belgium trying to get a better look at the damage his strike mission caused)
Pg. 123
"Willis was still dumbfounded as he followed the directions to the trolley stop. 'How did that man know I was an American?' was all he could think. A few blocks later the ability of the Belgians to identify Willis as an evader was again demonstrated. As he walked to the trolley stop, a young woman walked up beside him, put her arm in his, and said in English, 'I'm a prostitute, but I'm not asking you for business. I have V.D. and so I only do business with the Germans. That's the way I fight the war.' With that she let go of his arm and walked away. Willis could only look after her in amazement."
Moral of the story? That cute honey may still be bad for your long term health.
