 AITA... A little bit of context.   

&amp;#x200B;

I live and work in London and use a contactless method of paying for my travel to and from work. For those that are not from the UK a contactless system calculates the cost of your journey based on where you tap 'in' and where you tap 'out'. A one way journey costs me £3.20.   

On this particular day I forgot to tap 'in' when I got the train to work. The way this system works means that if you tap out without first tapping in, it calculates your journey cost as the maximum price in order to stop people abusing the system. Therefore tapping out would have cost me \~£10 (I'm not sure of the specific amount). On the journey I had realised my mistake and wanted to avoid having to pay the maximum fare and so went to speak to a railway employee.   

He listened to my explanation and my plea for help and then asked for my contactless card. After recieving my contactless card and checking that I didn't tap 'in' he informed me that taking a journey without a ticket is subject to a £20 automatic fine. He then proceeded to fine me £20 on the spot, using my contactless card to pay.   Therefore I ended up paying £20 instead of the £10 that I would've paid if I had just tapped out. 

By asking for a railway worker to help me in a situation where I had genuinely made a mistake I had inadvertantly cost myself £10.   I was so pissed off by this situation that after the railway worker fined me I told him that I hope he has a "fucking shit day" as well as some other colourful.language directed at what I think is a fucking ridiculous system.

   

So Reddit, AITA for telling this railway worker to have a fucking shit day?

TLDR: forgot to pay for train travel, admitted my mistake, was charged 6x my usual fare, took my anger out on the asshat of a railway worker.
