Every 6 months or so I have a medical appointment in a city roughly 50 miles away. A friend offered to drive me a few years ago and it has become a regular thing between us. I normally gave her £40 which after refusing & me insisting she eventually takes. I also normally treat her to coffee at the hospital.
With the cost of fuel going up is £50 more appropriate for 100 mile round trip?
Thanks for advice in advance.
