I've long been a proponent of churches leasing space to other organizations during the week. Many of us have large buildings with classrooms and kitchens and meeting rooms that are empty during the week. Now, of course, I also think that church activities should fill those rooms, but that just isn't going to happen all the time. So, for example, I think that having pre-schools in churches should be a regular occurance. We tend to have Sunday school rooms built for small people that stay empty outside Sunday mornings - and there is such a need for affordable day care.
Anyway, our church has a rental arrangement. A catering company works out of our kitchen. There are some downsides that I've encountered - for example, their business requires a lot of cold food storage space, which leaves the church with very little refrigerator/freezer space. But there are serious plusses too.
For example, right now I'm enjoying a mid-morning snack of strawberry pie because they made too much for a luncheon. Good things come to those who share their kitchens.
