Observe the difference in vending machines between canned soda and newspapers.
Typically, if you insert coins into a newspaper vending machine and open it you will see

newspaper distributor is relatively unconcerned about the rest of the newspapers being
taken without payment while the soda distributor uses a machine that goes to great
lengths to insure that only one can of soda is dispensed at a time.
