The greeting card industry used to put out statistics that confirmed that outside of Christmas the greatest purchase of greeting cards was Mother's Day with Valentine's Day a close second. Leaving Mother's Day aside because most mothers deserve at least a card, Valentine's Day is a guilt play for suckers. If you believe your spouse or S/O deserves a token gift, by all means do it. All women, including dancers, want to attach special significance to a day in honor of a saint who's very existence is questionable. (The claim was made that he was martyred because of his love of Jesus. This has morphed into a day for lovers.)
It's a day for guilt tripping guys into buying gifts. Dancers, by nature of the occupation, are manipulators, expect gifts and tips form RILs on Valentine's Day.
I prefer to stay out of clubs and avoid the SS on Valentine's Day. That may account for my limited OTC success, but that's another post.
