And the ticket inspector probably shouldn't have let you through, and you were probably travelling illegally until 0930.
But, hey, people get away with much more all the time.
I bought the ticket from a human being and told him I needed a 1 day travel card and needed to travel to Central London. Perhaps he misunderstood me and just sold me a travel card and thought I would be walking into the city. I noticed that when one departs from Heathrow, people show the ticket to a person, rather than put it into a machine. If what I was doing is illegal perhaps they should make people use the machines. Two humans looked at my ticket - one on either end, as well as the person who sold it to me.
