Richard, an impoverished university student, offers to keep the front and back yards of the family property mowed, and 'do a bit' to keep the gardens looking tidy, if his 'well-off' father agrees to pay him a weekly allowance. His father is happy with this proposal and agrees to pay him a weekly allowance of $200. Afterall, his father had previously used a garden contractor to do the job and paid him $350. They live on a one-hectare property, and the mowing alone takes half a day a week. After four weeks, Richard's father tells him that he can no longer afford to pay $200 a week. He says that Richard should be doing the work for free, as it is the responsibility of the whole family to look after the property; besides, he says, Richard is getting free board and lodging.
