I offered to pay my friend's petrol costs when she visits. It's approx 150miles each way, she drives a very small old car (can't remember the model but it's not one that would use a lot of petrol).
She says her petrol will cost £60. Is this reasonable for 300 miles?
I don't mind paying, but it's more than I expected especially as I'll also be paying for all meals out, drinks, taxi fares, day-trips etc.
