The most I've ever, EVER seen on someone else's bank receipt was $40K. I was so sick, ugh.
Granted, this was at a Chase either in Chelsea or the Meatpacking District. But still, the point stands and I may or may not have whispered "One day..." to the paper and let it fall like an autumn leaf.
Meanwhile, whenever I'm in Brooklyn/Queens/Uptown, I ki at the receipts and laugh at others' misfortune tbh.
