I've seen people try to spend bills that were obviously made on an inkjet printer.

Sadly, I've seen people that worked for the family owned bar accept bills that were obviously made on an inkjet printer. High rag content paper feels like real money and in dim light with an element of urgency (lots of people waiting for a drink) it's sometimes easy to miss.

Then there are those "magic pens" which are supposed to detect fake bills but actually just detect low quality (high starch) paper. James Randi, in his wild, younger days, would spray real bills with spray starch to cause a little chaos at the bank.

Terrifyingly devious while causing no physical harm. I wonder if pranksters these days are just as imaginative. Or perhaps the environment is less conducive toward appropriate penalties.

There’s also the potential that those people are in on it, attempting to launder money - “cheap drink, $20 counterfeit, $17 in real currency as change"
