The ones I have issues with are the collect at the station ones. I've had people say, oh i never had time to collect it, but here is my code.
The issue with this is Southerns Rainy Day policy. If the ticket is not collected a refund can be claimed and the T&C state the ticket must be collected for the trip or you will have to buy a new ticket. We have been looking at a way of noting the codes down so that when the person tried to claim a refund we can go, but you did travel, but thats a long way off at the mo.
On Southern we can end up carrying a Advantix, Chip and Pin, Oyster reader and Key reader.
And as for mobile phone coverage. Its very patchy on the BML with little to none between Three Bridges and Hassocks, its goes 5 bars to 1, to none, to 2 within moments, plus the Arun Valley is the same, plus Quarry, Balcombe and Clayton tunnels make life even more fun.
