I can see the food issue is becoming a recurring theme, and this is
detracting from the main reason I put forward this proposal. I have now
removed the food references from the proposal, such that now, the
subjects of the relation would be schools and medical facilities, whose
catchment areas are better defined, and of more use to more people.

Again, this proposal does not, and was not designed to address the
fragile nature of relations and I do not feel that this should be a
reason for avoiding adding this important information to the map (in
reference to medical facilities, pizza is slightly less important).
