Train

England is more or less well connected by rail, at least Derbyshire, the area that I know. You have to be careful with the ticket price because sometimes you can get a really good discount or a really expensive price, everywhere things work like that but the only thing I see different (It’s well known for everybody expensive prices) is why most of stations don't have a machine to check tickets to avoid evasion.

Below you can find a chat between a ticket inspector and a passenger.

Ticket inspector: Tickets please

Passenger: I have no ticket, please can I buy one?
Passenger thinking: Shit, he catches me.

Ticket inspector: Gentleman, why didn't you buy one before get on the train?
Ticket inspector thinking: I catch you and you know what that mean but I have to be polite.

Passenger: I am really sorry but it was raining.
Passenger thinking: because I didn't want, I never thought I would be caught.

Ticket inspector: but the machine is under cover.
Ticket inspector thinking: another smartass, you know that to use the train you have to pay one.

Passenger: I told you, it was raining and I thought I could buy a ticket inside the train.
Passenger thinking: I didn't buy the ticket because I have been using enough time the same train how to know never tickets are checked, probability, you know??

Ticket inspector: I am sorry but your story is not valid, you will have to pay a fine
Ticket inspector thinking: I know you are playing with probability, but we are doing the same so if I would sell a ticket now you would only pay tickets when you were catch.

Passenger: I am not agree, I want to buy a ticket now.
Passenger thinking: I have to insist, I might get him tired so he sells me a ticket, and everybody knows you can get a ticket inside the train.

Ticket inspector: I am sorry but I cannot sell you a ticket now, if you don't want to pay the fine you have to get off in the stop and follow me.
Ticket inspector thinking: I catch one evader and the rest of travellers will realise they could be catch too. This is the reason because I am having a walk trough the train.

Passenger: OK
Passenger thinking: Shit, shit, shit.

I mean, I don't understand why ticket inspectors spend the whole day, day after day, repeating the same speech, ticket inspectors check tickets on many trains and staff carry out undercover operations to detect persistent fare evaders. If fare evasion is rife and costs around £50 million annually it would be easier and cheaper if you had a way to control that everybody has a ticket.

Conclusion's passenger: ticket price is too expensive how to try don't be catch.
Conclusion’s ticket inspector: if my company prefer to pay evasion costs around £50m plus salaries ticket inspectors instead installing machines to control it, how much are they earning with fines??
