So on the train service in question you are not allowed to bring non-folding cycles onto the train without booking them in in advance. There are 2 cycle spots in alternate carriages of the train. Folding cycles can be brought on as luggage without booking.
I have a folding cycle. I did book a cycle spot anyway on the train but the cycle reserved point I have been issued with is in a different carriage to the place my booked seat is and I don't want to have to struggle down a crowded aisle to get to my bike when we get to my destination station, so I folded my bike up (so it's smaller than a hand luggage size wheely suitcase) and stowed it in the luggage rack at the end of the carriage.
The train journey continues and at the next station a couple who are clearly in a relationship (very tactile with one another) get on. man in his 30s with a woman slightly younger. He sees my bike in the luggage rack and says something like "why on earth has someone put their bike there? Selfish bloody cyclists!" (Rants a bit more about cyclists but I don't recall exact wording.) He puts their wheely suitcase, which is bigger than my bike, onto the overhead rack and they sit down and spend their journey absorbed with one another's company for half an hour or so before disembarking at their destination.
So obviously I have no intention or opportunity to say anything to him but am I actually being selfish to use the luggage rack?
It could not be safely stowed in the overhead rack as it would wobble, and I can only assume that the cycle spots in this carriage have been booked by other travellers or the train booking system would have assigned one to me, so I can't reasonably use one of them.
