Just remembered this time my old boss asked me to stay after work, stating he had a wonderful financial opportunity for me. He played it up that I was the perfect fit and he'd specifically chosen me for the opportunity. Thinking it was something type of promotion, I paid for my kids to stay in the after care program so I could attend the meeting (which was money I didn't have at all) .
Turned out he was trying to get me to sign up for an MLM he was part of selling cleaning supplies.
