Where it was once the case that a passenger had to visit a booking office or agent to buy and pay for a coach ticket, the introduction of on-line Internet booking methods removed what today would be considered a great inconvenience.

The way of the world I suppose that tickets aren't what they once were or maybe don’t even exist.
Most passengers don't even know what a paper ticket would look like, they just show their reference number on their mobile phone screen to the driver and that's it.

Not being into mobile phone apps myself I chose to print my ticket at home for a journey between Cambridge and Birmingham and present this to the driver but to me an A4 piece of paper doesn't quite have the same charm and souvenir value as a colourful printed ticket of old.
