Hey, I am hoping someone can help.
Man A is ill, he sees Man B and asks if he would be able to carry out a task for him of delivering leaflets, Man B says yes to which Man A sayas thank you and I will repay the favour.
Man B carries out the task, after the task was completed, Man A says you did a great job I shall give you a voucher, come and collect it., Man B turns up and Man A says sorry, I can't afford to give you the voucher.
Advise Man B
Its at Uni Level.......
