Well, there are two possibilities – let’s discuss each of them.
Scenario 1 – Maybe the machine is full.
If you see a machine with a “stop” sign on its display, empty the machine before continuing. If this is not possible or if you are unable to speak to an employee, be sure to request their help before leaving.
Scenario 2 – The machine may have some fault.
Suppose the recycling machine is not broken/defective, but you only have one other device left. In that case, you will be allowed to place the bottles on your conveyor belt, and the cashier will manually count and dispose of each bottle in big cardboard. The total deposit that you make will be deducted from your final receipt.
