Once a family came to me on the train asking me if i can move and give them the seats , this carriage was full but all other carrages were empty. I was also eating food at the time, i packed my food in my bag and simply left them the place without saying a word and went to another carriage. Simply did not want to get involved with idiots as i wanted to eat and relax for my 4hour train ride. Its not being a cowered, just not worth the drama, time is limited and creating drama wont get you anywhere.
It would of been a diffrent situation had there been no other seats, as i came early i took the seats hencforth i am entitled to them.
