+1, they'll most likely make an exception also for small orders if it is for a place a few steps from the "border", while they will probably make exceptions for larger orders also if it is a little more distant. IMHO for pizza services a less intrusive way of storing catchment areas would be more suitable, like a radius in kilometres/miles, or a reference to existing more official areas like administrative boundaries or place polygons. It might also be a distance like 10 km where this is the real distance (routing) and not as the crow flies. These would be ways to store useful information without putting load on the db and with very little risk of breaking compared to explicit relations. As others have pointed out: if you look how often the very important polygons like administrative areas or the coastline breaks, it is very likely that potential explicit and individual catchment areas for each and every pizza service will most of the time be broken. cheers, Martin _______________________________________________ Tagging mailing list [email protected] http://lists.openstreetmap.org/listinfo/tagging
