Better to run and look like a coward than to get bit. Looking like a coward in front of a stranger costs you nothing. Misjudging a dog and getting bit can cost you disfigurement or death. You know your dogs; the appliance installer doesn't.
Also, I think it says something about the temperament and worldview of the owners of these dogs that they so often seem very concerned with appearing brave or cowardly.
