               Notes

    In Britain Meals on Wheels is the name of a service whereby meals
are prepared in some central place and then delivered in a van (i.e.
'on wheels') to individual old people in their own homes. Usually the
old people pay a small sum for the food, but the delivery is made by
unpaid³ voluntary workers (the Women's Voluntary Service).
