Some companies, e.g. FCC and Southern, allow up to four children aged 5 to 15 years to travel Off-Peak for only £2 each when accompanied by an Adult with a valid ticket.
You can only buy these tickets from a ticket machine if you are also buying the adult ticket. Otherwise you have to buy them from the ticket office.

What do you do if the ticket office is closed?
Condition 3 says " you must buy a ticket or Permit to Travel before you travel that entitles you to make at least part of the journey", but there is no ticket costing less than £2. So do you buy a full price ticket and then get someone to refund the difference? And if so who?
