My usual Northern semi express between Meadowhall and Leeds is typically standing room only between Wakefield and Leeds each way - it becomes a problem when the usually rammed CrossCountry service gets cancelled or delayed, in which case the speed freaks transfer to my semi fast service.
I stopped using the CrossCountry service due to the lack of seats, the stopping service down through Swinton is just too busy and takes too long... So yes, I've adapted and accept a slightly longer trip as a trade off for getting a seat and free parking at Meadowhall - the fast service would be nice, but means I'd not get free parking, plus i'd have a. 40 minute tram ride home and a 10 minute walk to my house rather than the 15 minute drive, so the semi express actually is faster for me.
The moral is yes, you are correct, if passengers don't like it, adapt to suit your requirements - which might mean a different slower service, might mean using different stations, might mean different modes of getting to your stations... The railways ain't going to change to suit one person
