Wait, she banged you in a three-way, then detailed and filled up your car? Jeez, if she’d just pressure-washed your deck and killed your crabgrass, you’d have the Middle-Aged Suburban Guy Sex Fantasy trifecta.
I would never use a credit card for a cash advance, even for my actual best friend (myself).
I’m not saying you should help anyone, but if I wanted to use my credit card to help a friend (I have for close family) I would maintain possession of my own credit card and use it at the point of sale or order something on someone’s behalf. For example, I’ve used my card at a gas pump for desperate siblings. If they “need” cash, I can’t imagine it’s for anything other than drugs.
Like, “T-Minus, if you lend me $10 I’ll be your best friend”? I knew people like that back in the day.
