The Steaks Are High
Meat is one of the most expensive things you can buy at the supermarket, which is why this ex-employee’s loophole is nothing short of brilliant. The grocery store they used to work at was offering “$5 off a steak” coupons and for some reason, the OP had access to hundreds of them.
They even discovered that if they used the coupon to buy a steak that was less than $5, the self-checkout machine would give them back the difference in change. Not only did they eat tons of free steak but they also filled up their piggy bank and never got caught.
