“I lived near a casino that would let you get chips using your credit card. I liked some of the shows and restaurants there but never gambled. So every time I went I’d charge $5K to my credit card for chips. Then I’d cash out at a different teller swing by the bank on the way home deposit the money and pay off my credit card. I did this maybe once a week. Boom $5K of free points / cash back.”
