Coffee.

Now before you get upset, my company spends thousands of dollars a month on shitty coffee beans, rented coffee machines, and a monthly cleaning service for those machines. They purchase Peet's coffee which is expensive but tastes like brewed cigarette butts and brew it in standard drip coffee machines that cost the equivalent of 3 new coffee machines each month. Most of the employees don't even drink the coffee, they brought their own Keurig machine and brew their own pods instead.
