The staff at the ThamesLink ticket office at St.Pancras are useless and frequently sell me the wrong tickets then have to cancel them, and then
re-issue what I requested in the first place. Frankly a ticket machine would be better - except they don't offer the extension tickets I need.

I had a problem with that office. I needed a ticket that the machines
didn't sell: because it was for "tomorrow" and "not from here". I was
doing a triangular trip flying out of Gatwick and returning to Luton,
and thought I'd buy the ticket for the once-upon-a-time free shuttle bus
to the MML station in advance.

Despite asking for what I wanted several times, the chap simply refused
to comprehend. Eventually he issued me with a ticket from Parkway to the
Airport. I gave up.
