If they're not afraid to say they didn't write it, why not say who you are. Also, since she donated all her money to charity, I don't think it was about the money for her.
"She later said she planned to give a portion to the Wounded Warriors Project." No. I myself appreciate anonymity from time to time, and maybe this couple doesn't want to be the center of attention.
It might not be about the money. Some people want their 15 minutes of fame. I don't know who'se telling the truth at this moment, but I know it's certainly possible it's a hoax. If it is, it's a shame, because theirs enough real homophobia in the world without this.
With ways that people on the Internet will track down and torment people they don't like, I would say that desecration is the better part of valor.
There was also the notation the slash for no tip that the wife supposedly did - she is saying she could not have done if it is examined it was drawn right handed and the wife is left handed
There's no proof she's the one who did it though. It honestly wouldn't surprise me if the manager did it to get more customers in. (As the last time this happened, the place it happened at got flooded with people wanting to be served by them.)
