h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

I went to the rail station for the (standard-class off-peak) return
ticket to Hebden Bridge. I was quote a price about twice what I
expected. I returned to the PC to see if I'd misremembered the figure
I was thinking of (I hadn't). The National Express web site showed
that, if I travelled by coach and bus, I wouldn't be able to make the
Friday evening meal. The National Rail Timetables web site mentioned
"super advance returns". I checked various alternatives for a main leg
of the rail journey, and it seemed that super advance returns for the
appropriate days were no longer available. Mentally grovelling, I
asked at the station again. The man there tried a few times and
eventually found me a super advance return for about 75% of the
earlier higher price. I have a printed itinerary; the only legs where
I must go on a particular train (for a particular booked seat) are
London King's Cross -- Doncaster out and Leeds -- London King's Cross
returning.
