Travel arrangements for Eddie

Eddie lives quite far away in Withernsea/Hornsea, Eddie has his own car so therefore he is able to travel to me, because he is travelling a large distance and will be travelling a lot to get the shots done, I have spoken and arranged to give him money for his petrol, around £30 is the price that I will pay for his petrol which is understandable because he is doing this voluntarily for me and he is making his own way to me. Also he is at college so he isn't in full time employment which means he doesn't have a lot of money to spend on petrol.
