I cut our grass last night, and the neighbour's, too. Her mower was stolen from her patio a couple of months ago after a car demolished the fence.
Anyway this morning she popped round with some money in an envelope. She doesn't want to bu another mower for fear of it being stolen again, so she prefers to pay someone - me if I want the job - to mow her lawn. It's not a big lawn. It takes ten minutes, perhaps, to cut it. I'd happily cut it for nothing. For a piece of cake from time to time. For neighbourliness.
Now comes the dilemma. Can you politely refuse payment like that here? Or should we save up the money and buy really nice food when we get the neighbours round for cake and coffee? (I suppose I could put it towards a trip to Evian in a couple of years' time!)
