No. She could have given you a ride if she was going there anyway.
No peasants!!!
Why should she give you a free ride?
How did you expect to get home after the interview? Were you going to wait around 8 hours for her to get done with her job? I highly doubt it.
And it's not her fault you missed the interview. It is completely your fault. You could have walked, biked, taken a bus, taken a cab/Uber.
Why do you have to depend on other people? You should have prepared yourself much early for that interview. Don't hold people responsible for your benefit.
How much did your friend want for gas?
Your priority should have been getting to the interview.
You could have decided later whether or not she was a "real" friend or not later.
And her desire for compensation may be part of her personality and an expectation on her part.
If it is, then you need to accept that or not ask her for favors again---and then decide what kind of "friend" she is.
