jack transaction
A group of people chip in for a meal, but one guy takes the cash, pays with his credit card, and then gets all the cash back, points, and makes his company pay for it. You're the one who got jacked.
I put $15 in the meal pot. Jack takes it, pays with his card, and I’m out $15 with no cash back. He’s rich and I’m broke.
We all chip in for lunch. Jack takes it all, pays with his card, and I get the bill and he gets free points.
Jack takes all the cash from the meal pot, pays with his card, and I'm left with the bill and a side of frustration.
