We have a couple of vending machines at work that are chronically ill. The first, a Pepsi bottle dispenser has a constant full row of bottles. The remainder of the machine can be empty but C7 will remain full. At some point one might believe the vending machine operator might get the wiser and figure out the machine errantly says the row is sold out. Several months have passed and the problem persists.
On the other end there is another machine with slot 22. Slot 22 is consistently filled with the last tantalizing bag of Cheetos. The rest of the machine is largely full and only the Cheetos are so low. The bag remains stuck, as it has been for several weeks. When do people stop looking at such things.
