Short version: Some people are predicting societies going cashless, exclusively digital/credit card system. This makes me wonder how strip clubs and other locations that rely on using lots of bills for tipping/"making it rain" will be impacted, and how they would transition.
Long version: A friend of mine was recently telling me about a trip abroad he took where he used no cash, exclusively digital currency, sort of like paying for everything through paypal, no cash or even credit cards, all done on phone. I've read a few people in newspapers (can't find links now unfortunately) predicting various countries going cashless, and a number of stores/restaurants near me don't accept cash at all now.
This made me wonder how strip clubs would function if you couldn't hand tips over. Best thought I have is a sort of monopoly money system that you buy at the start, like poker chips except you wouldn't want to throw poker chips at people.
Has anyone thought of this or have any ideas?
