Inertia

Scene: the queue at Lidl. Opposite me is a guy who is buying two items - one is a 2 litre bottle of some drink or other. He has laid it across the belt. Every time the belt lurches forwards, the bottle predictably attempts to stay where it is and rolls 'backwards'. This comes into conflict with his place marker and once or twice dislodges items from the stack of the person following. Several times, he rearranges the bottle further forward.

I wonder whether he has any notion of inertia, and how he could simply lie the bottle down with its long axis along the belt to avoid this repeated learning opportunity.

At least, he didn't stand the bottle up, and have it fall over each time. There might yet be hope for humanity.
