Uhhhhh honey what you're describing is called "theft". Also known as "fraud" if you want a different name.

But to answer your question, I usually shit during working hours, so I get paid to shit. It's a great feeling.

Someone I worked with did something similar. This was close to 25 years ago, at a popular drive thru corporate coffee chain. I took no part in these shenanigans myself, but I got a cut each night we worked together just for looking away as it happened.

Basically, her whole hustle revolved around the fact that the cash register at the drive thru window had been broken and not working for ages. She had memorized the prices for every single item sold there. So when someone ordered at the drive thru, she would tally up their whole order in her head, but then go around to the main counter's register and ring the entire order up as just a small coffee. She'd then take their money, give them the change that was due, but put the difference into the tip cup.

This went on for about a month until I just couldn't stand the overall work environment. It's still to this day the only service industry "job" I've ever had. I hated it so much that even all that extra free money couldn't keep me there.

Hating that one month so much is also the reason I tip service workers as best I can, still to this day.

absolutely. I work at a phone/computer repair shop.

I have a policy called the "front desk fix policy". pretty much, if I can fix it at the front desk in under a few minutes, I'm not charging you for it. common culprits are simple software fixes and charging port cleanings.

I give free screen protectors with every repair instead of charging customers for it. the screen is the expensive part not the screen protector.

I also tend to give a 10$ discount if people are just cool to talk with. if we genuinely enjoy talking to each other, they've made my day better, so I might as well do the same for them.
