I'm going to not give up my seat so quickly.
Why do you feel the need to refuse to give up your seat so quickly?
I've heard lots of bad stories about how people were taking advantage of me.
Being taken advantage of is not that easy to deal with. But it is also a wrong thing to do if you don't give up your seat to someone who might really need it more than you. Give your seat up and have someone disabled sit there so you can have a better conscience.
If a pregnant woman, an elder or a disabled person needs a seat then I'll give up my seat but not for anyone else.
That's fair enough. Those type of people don't look to take advantage of anyone. It would be a great gesture to offer your seat.
