"I couldn't believe, just by clicking the wrong button... that it counted as criminal activity. I was really shocked."
Molly McGregor has not had a fun time travelling on the railways recently.
In June, the 29-year-old commuter was threatened with prosecution for selecting a 16-25 discounted train ticket instead of a 26-30 one from London Bridge to her home in St Albans. They both give the same discount.
That case has now been dropped after her MP intervened. But it was only when challenging it that Molly discovered she had also been prosecuted for a separate incident the month before.
