I think the people who assume the OP was serious need to update their Sarcasm Detector to the latest 3000-series model, available for only £16.99 (inclusive of postage and packing) from reputable outlets such as Temu and Amazon.
I sympathise with the OP. I travel semi-regularly from Slough to points west and north, journeys which are most easily made with a change at Reading. It's an endless nightmare. When I get off the Elizabeth Line train and head to the GWR platforms, it's like being in an ant's nest. Throngs upon throngs of people, all fleeing to Plymouth or St Austell or Bristol or Newport or goodness knows where; pushing, shoving, jostling. It's literally impossible to tell where the join is between platform 8 and platform 9, ridiculous. And then you get on it, which is a nightmare in itself. The GWR trains are
specifically programmed that the last seat is taken the moment you get on. It doesn't matter whether you're at the front of the queue or the back: you are always the first standee. Every time. Either the empty train has been swarmed by the people in front of you on the platform, or it's already full of anonymous Londoners who have nothing better to do than ride to Newton Abbot and back simply to take up a seat that could have been yours. This is a significant overreach by the state and proof of the appalling specifications of the Class 800/802 stock. And when there is a seat, it's almost always taken up by the Invisible Man and his lap is even more uncomfortable than the seats.
Don't even get me started with trying to get off the train on the way back. The IETs have only one door leaf per door. This is a disgrace. No successful item of rolling stock has ever had one door leaf per door (except for Mk. 1 coaches and derivatives thereupon, Mk. 2 coaches and derivatives thereupon, Mk. 3 coaches, Mk. 4 coaches, the Class 444, the Class 220, the Class 221, the Class 222, the Class 156, the Class 390, and the Eurostar units, but we can ignore them). Two door leaves is the recent fashion, but ideally all new stock must have three door leaves per door. This must be a national standard, or I, as the only person ever alighting at Reading, will continue to be flattened by the hordes of people trying to escape onto the train. Literally that one time I got knocked over by this lout with a bike, nine suitcases and a horse because we had to share a door. The rights of we Southerners to impatience must be respected by the state. Never used to happen before King Charles got in.
Where do all these people come from? They can't come through the entrance; nobody ever goes there. Gateline staff paid a fortune for nothing, broken Britain, going to the dogs. Anyway I tried to exit the station once. Put my ticket in, as you do. Stupid barrier then shouted at me, inconsiderate so-and-so. Wouldn't let me through. Kept refusing to believe I was real. No staff anywhere either, broken Britain, going to the dogs. Why they want Reading to be a city I'll never know, with this mass exodus there are probably only three people left by now. Horrendous confusing mess of a station, why nobody does anything about it I'll never know. One day someone will get stuck in an endless loop while making the station look busy and then the railway will look silly. And the platform numbering is discriminatory against people who can't count past 10. Whose idea was that? It means I can only get halfway across the footbridge before stopping dead and looking confused. In fact, I'm still there now.
Sadly, nothing will change; the railway is so anti-passenger and if they listened to me things would be far better.

(P.S. I love fun little threads like this: a nice antidote to the rather grey state of the world at the minute. Thanks for the rant OP
