Back in the day, when I visited NYC from Connecticut, it was standard operating procedure to split the majority of your cash amongst your person - both socks, a couple of pockets, and $30 in your wallet - just enough to keep the thugs from getting angry at the lack of a good haul.
Yeah. It was important to give any muggers back then enough cash to buy drugs with for their next fix, or they’d get very angry with you for not carrying enough. Also, it was essential to give them the impression that they’d gotten everything of value that you had.
