Our kids were amongst a group of sixteen church teenagers (Under 16s) booked to go from Manchester to Eastbourne for a weekend. Long and expensive journey by train!
However, we happened to have four young adult youth leaders going, so they each bought a Family Railcard, with a parent designated as second-named holder on each card. Thus all the "children" travelled for £1 each (this was several years ago) with the young adult leaders getting a discount as well.
After the weekend, four families then effectively had a free railcard for the rest of the year.
Elaborate? Up to a point. Evasion? Probably, I'm sure the railcard was not meant to be used in this way. Legal and honest? Perfectly! Literally saved hundreds of pounds.
Oddly enough First Manchester Buses have a family day ticket which is for two adults and two children, quite often when couples are boarding the driver will offer them one of those tickets as it works out cheaper than two adult day tickets. Despite my opinions on that company they do have some friendly drivers who will offer the better choice of ticket, like issuing a "night-saver" (valid until 3am) rather than a day ticket which costs a bit more (Night tickets can be issued after 5pm, day tickets are issued at any time). I do wonder how much the company makes selling day tickets after 6pm to then sell a single night ticket after midnight to the same passenger?
I digress...
Back in my plane spotting days I used to travel from Salford Crescent to Manchester Airport every weekend, early on a Sunday morning the office would be closed, if the guard didn't come through on the outbound trip nor the return we got a free trip (I don't think they had a booking office at the airport station back then).
I'm not sure what this one can be classed as but it was definitely inadvertent. A few years ago back when I was still air crew I was making my way home from Crawley, I'd been to the pub and was heading back to meet some friends at my local so I decided to take the train as it was quicker than the bus. The ticket office was closed but they had two ticket machines, I go up to one and select "Three Bridges" and put in what I thought was a ten pence piece, it dropped out so I tried again only for it to be rejected once more, I gave it a rub (why do we do that with coins?) and tried again - success!
The only thing was, my coin was returned yet again but along with a printed ticket and change. Now believe me the fare was certainly not less than 30 pence so I looked at my coin and sure enough I'd put in a Barbados 25 cent coin (which is minted exactly like a 10p coin) but for some reason that machine didn't just reject the coin it also thought it was a pound coin and thus thought I'd put in 3 £1 coins, hence the change.
This was not the first time I'd got one of them 25c coins mixed up, I did it at Gatwick after a flight but the machine rejected it straight away so either there was something wrong with that machine at Crawley or the machines at Gatwick are more wisened up on the differences between British & Foreign currency.
As an aside, when I've been working in retail I've had many people passing me overseas coins when paying, though the fake one pound coins are a pain as bar staff and bus drivers seem to not notice them (which in a way offers an avenue of palming off dodgy coins when one has been the recipient of such coins - usually in a packed bar)
