I just watched the below scene as Full Metal Jacket is on the TV at the moment. I remember as a kid when I first saw it on video and was like, WOOOOOOO you can pick women up on the street and pay them for sex, from then on I think I have always have had fond memories of it.

But when watching it now, I noticed the the prostitute was coughing and Joker mentions that half the Vietnamese prostitutes have TB and it got me wondering if this was a paid for "plant" in the movie to discourage cinema goes from availing of prostitutes, you know the way that James Bond wears an Omega watches?
