Roses? Seen term in Craigslist erotic section. People offering roses for 'services'. Why?

Question

actual roses? something else? www.craigslist.org erotic section has offers where roses are a payment. What purpose does it serve?

Answer 1

It's a code word for something else....THINK PINK!! They don't want to get busted for selling sex

Answer 2

I think they use the term roses instead of dollars so as not to incriminate themselves by revealing their intent to prostitute themselves.
