Reminds me of a guy who wrote to an advice column. He started dating a single mother. As their relationship progressed, it came time when they were going to engage in sexual relations for their first time in this relationship. They got undressed and the guy recognized a tattoo on the woman’s body. He realized that his girlfriend, this same woman, was a prostitute whose services he used years back. He asked if he should tell her that he recognized her. (The advice from the columnist was no)
Probably a bad tipper.
