Local rescue organisations and populace are accustomed to the service and the service provider that they already have. People are naturally conservative and distrust anything new or different. For example, people stay with the same Bank/Building Society for years although they could get better and cheaper service elsewhere.

Ditto Lossie, Chivenor etc...
