Q: I currently live in Pretoria and work in Jet Park (I travel about 128km a day to and from work). Currently I use my car everyday to work and back. I have previously looked at the Gautrain as an alternative, however it worked out a little too expensive for me.
Recently, my small brother informed me that he receives a discount on his Gautrain trips (as he is a student) but doesn't use this discount as his campus isn't so far and it's easier for him to drive. As he isn't using this discount- He had offered it to me to use his discount to travel to work.
My question - Would it be permissible to use his discount for my benefit (considering he is a student and I am not)?
