Petrol prices here in England are extortionate...£1.15 (up to £1.30) per litre is maybe average....that's £5.23 per gallon...which is $10.38 per gallon.
I don't believe the Org cares about petrol prices...and one extra (short) journey a week is irrelevant...does this mean Field Service will be 'subsidised', as all Charities that I'M aware of (and I used to work for one), compensates their unpaid volunteers for petrol money....and the WT IS a 'charity'.
I agree with other posters...this is about control and 'subliminal messages'
