A very toxic industry to be in, I used to be an engineer for a company that looked after slot machines here in the UK. High Street betting shops would regularly get smashed up by people after they lost all their money, but they would just pay us to repair them and let them back a few weeks later because they knew they’d be back. Completely taking advantage of people with a very real problem.
I saw a video on YouTube showing how to use them for knitting gloves, you can still buy plastic versions
