Afterwards, you just refund your ticket. You could also do that with a cheapo ticket with a 10EUR fare and lots of taxes, just claim the taxes back at a latter point, so this thing just cost you something like 10EUR.
What you can do is, buy a ticket at the ticket desk and you can cancel it within 24 hours without any charges. Check-In, meet the person and then cancel the ticket.
