Inspired by this question...
The local council require a fee for the collection of certain refuse. In certain cases there are those who have a bin with all their garden waste that is picked up once a week.
What happens if it is discovered that the collection is on Shabbos. The result means that people have paid (albeit in advance) for a goy to come and do a service on Shabbos.
As a result, is one allowed to let this happen? - i.e. should they explore other options in order to remove the waste, or since they have already paid and the council chooses to come on Shabbos, something they have no say in, can they just let them do their job?
